Question

Y=x-5
y=7
solve for x
simplify your answer as much as possible

Answer 1

x = 12

Explanation:

First of all, what you will want to do is plug in your y into the first equation, to find the x.

y = x - 5 ----> 7 = x - 5

Next, think about your possible solutions here.... Flip the equation:

5 + 7 = ? ---> 5 + 7 = 12

Now, plug both your x and y in the original equation:

7 = 12 - 5 Does this match?

7 = 7 Yes!

This is the simplest way I can explain it! I hope it is understandable, correct, and helpful. Have a great day :D
