13 ? 15
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.

13 ? 15
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
If you mean: x^2+15-3x then its value is 19 when x equals 4
15 (x = 135)

5x - 8 = yWhen y = 1,5x - 8 = 1Add 8 to each side of the equation:5x = 9Divide each side by 5:x = 9/5 = 1.8
