Question 11845
I think instead of solving for x, they want you to just substitute the value of 7 in place of all the x's.  If it comes out a true statement, then it's a solution.  If it is a false statement, then it is NOT a solution.


2(x -2) - 5x = 5(2-x)
2(7-2) -5(7) = 5(2-7)
2(5) - 35 = 5(-5)
10 - 35 = -25


Since this is a true statement, it is a solution!
