3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
It is an expression that can be simplified to: 3x-20
3x-1=11 3x = 12 x = 4 Then, x^2 +x = 20.
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
3x+5=20 x=5 since 5x3+5=20
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
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.
20+6y is the equation simplified, but there is no way to figure out the answer.

3x-1=11 3x = 12 x = 4 Then, x^2 +x = 20.
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
3x+5=20 x=5 since 5x3+5=20
(3x + 5)(3x^2 + 4)
That will depend on the plus or minus value of 20 or perhaps there is an equality sign missing and so therefore it has no solution.
-3x + 5 = 20 -3x = 15 x = -5
If you mean: 20 -3x = 14 then the value of x is 2
