Question

y=2x=5 y=3x-3

Answer 1

hey valerie - did you mean 7=2x+5?

Answer 2

err sorry, 7=2x+5

Answer 3

(you wrote "=')

Answer 4

if that's what you meant, then what you need to do is substitute the value of y from one equation into the other

Answer 5

so let's take y=2x+5 , and substitute the value of y (2x+5) into the other equation (y=3x-3)

Answer 6

so
1. 2x+5 = 3x - 3
2. 2x + 8 = 3x
3. x = 8

Answer 7

now I'll leave it for you to ask more questions, or substitute x=8 back into either equation to get the value of y
