Mixed Operation Pre-Algebra Problems 12 Pre-Algebra Worksheets These pre-algebra worksheets require solving for the missing value in addition, subtraction, division and multiplication number sentences. Mixed Operation Pre-Algebra Problems Printable Pre-Algebra Worksheets Before we introduce that dreaded variable x into the lives our young students, we can take one more pass through conventional arithmetic with these pre-algebra worksheets! Equations Are Just Number Sentences with an Equals At it's simplest, solving algebra problems involves figuring out some unknown value in a number sentence with an equal sign, more formally known as an equation. These worksheets provide simple number sentences that are missing a value and kids will need to figure out what the value is using their existing knowledge of the basic math operations.
Graphing linear equations Word problems Video transcript Let's do a couple of problems graphing linear equations. They are a bunch of ways to graph linear equations. What we'll do writing algebraic equationsworksheets this video is the most basic way. Where we will just plot a bunch of values and then connect the dots.
I think you'll see what I'm saying. So here I have an equation, a linear equation. I'll rewrite it just in case that was too small.
I want to graph this linear equation. Before I even take out the graph paper, what I could do is set up a table. Where I pick a bunch of x values and then I can figure out what y value would correspond to each of those x values.
So for example, if x is equal to-- let me start really low-- if x is equal to minus or negative 2, I should say-- what is y? Well, you substitute negative 2 up here. It would be 2 times negative 2 plus 7. This is negative 4 plus 7. This is equal to 3. If x is equal to-- I'm just picking x values at random that might be indicative of-- I'll probably do three or four points here.
So what happens when x is equal to 0? Then y is going to be equal to 2 times 0 plus 7. Is going to be equal to 7. I just happen to be going up by 2. You could be going up by 1 or you could be picking numbers at random. When x is equal to 2, what is y? It'll be 2 times 2 plus 7.
So 4 plus 7 is equal to I could keep plotting points if I like. We should already have enough to graph it. Actually to plot any line, you actually only need two points.
So we already have one more than necessary. Actually, let me just do one more just to show you that this really is a line.
So what happens when x is equal to 4? Actually, just to not go up by 2, let's do x is equal to 8. Just to pick a random number.
Then y is going to be 2 times 8 plus 7, which is-- well this might go off of our graph paper-- but 2 times 8 is 16 plus 7 is equal to Now let's graph it.
Let me do my y-axis right there. That is my y-axis.Use the handy online video lessons in this Writing and Solving Two-Step Equations chapter to teach your 6th-8th grade students various methods for solving algebraic equations.
