We can apply a technique I call the Something Methodboomgoesthegmat wrote:If y[(3x-5)/2] = y and y does not equal 0, then x =
A) 2/3
B) 5/3
C) 7/3
D) 1
E) 4
Given: y[(3x-5)/2] = y
We have y(something) = y, so that something must equal 1
That is, (3x-5)/2 = 1
If the fraction equals 1, then: 3x - 5 = 2
Add 5 to both sides to get: 3x = 7
Solve: x = 7/3
Answer: C
