Multiply out the parentheses and combine like terms.
4x +20 = 3x -12 + x = 4x -12
There is no solution. The two sides of the equation correspond to parallel lines.
4x + 20= 3x +12 +x
4x + 20= 4x +12
You would minus x from one side to the other which would give you 0 x so there is no x. 0=8
what number is greater than 25 less than 35 and 5 more than the number in the tens place
