Find the value of y when y=3
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
X = 135 and y = 15 Solved by addition and substitution
If you mean: x^2+15-3x then its value is 19 when x equals 4
x=100
x=7 ft.

15
13 ? 15
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
x/5 = 3 Multiply both sides by 5 to find the value of x:- x = 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.
X = 135 and y = 15 Solved by addition and substitution
15 (x = 135)
If you mean: x^2+15-3x then its value is 19 when x equals 4
