Question

When you solve a system of equations, explain how you can determine if your solution is correct

Answer 1

What you want to do is you want to substitute the answer into either the first or second equations of the system of equations. For example, if y = 7, you would plug y into an equation like this:

1. 4y +3x = 46

4(7) + 3x = 46

28 + 3x = 46

28-28+3x = 46 -28

3x = 18

3x/3 = 18/3

x = 6.

You should get your answer. For a 7th grader like me, it was pretty tricky, but you'll get the hang of it.
