What is the value of y if x = -3?
y = 1 = 2(x-5)
Plug in -3 for x, in the equation for y, and see what you get.
I think you copied the problem wrong. Is the first = sign supposed to be a + or - sign? If not, you have already stated that y = 1. That cannot be true when x = -3.
I agree with drwls. It has to be a coping error. Ask this question again and look at the problem and I will be glad to answer it.
