hey valerie - did you mean 7=2x+5?
OpenStudy (anonymous):
err sorry, 7=2x+5
OpenStudy (anonymous):
(you wrote "=')
OpenStudy (anonymous):
if that's what you meant, then what you need to do is substitute the value of y from one equation into the other
OpenStudy (anonymous):
so let's take y=2x+5 , and substitute the value of y (2x+5) into the other equation (y=3x-3)

so 1. 2x+5 = 3x - 3 2. 2x + 8 = 3x 3. x = 8
OpenStudy (anonymous):
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
