System of equations by substitution
how do this?
y= x+2
y= -4x+7

Equations are given,
y= x+2

y= -4x+7

As you can see both the expressions, x+2 and -4x+7 are equal to "y". That means they are equal to each other too.

So let's equal them and solve it.



Now we have x's value we will plug it in the first equation to find "y".
