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
If you mean: 20 -3x = 14 then the value of x is 2
If: 3x+20 = 2x-10 Then: x = -30
You haven't given the solution to the equation ! 3x + 20 = ? If you have the number for the question-mark - you can find the value of x ! For example in the equation 3x + 20 = 50... the value of x is 10.
The value for x is 13. 10 x 13 = 130. 3 x 13 = 39. 130 + 39 = 169.
3x-1=11 3x = 12 x = 4 Then, x^2 +x = 20.
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
3x-1=11 x=4 x^2+x=20
3x+130+65 = 360 3x+195 = 360 3x = 360-195 3x = 165 x = 55
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
3x = 60 Divide both sides by 3 to find the value of x: x = 20

3x-1=11 (3x-1)+1=11+1 3x=12 (3x)x(1/3)=12 x (1/3) x=4 x^2+4 16+4 =20
