Assuming you mean 3x-20=130
3x=150
x=50

If you mean: 20 -3x = 14 then the value of x is 2
The value for x is 13. 10 x 13 = 130. 3 x 13 = 39. 130 + 39 = 169.
3x - 1 = 11 so 3x = 12 so x = 4, so x^2 + x = 16 + 4 = 20 3x=12 so therefore x=4 x2 + x = 16 + 4 = 20
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
