Given the equation:
2x + 4(2x + 7) = 3(2x +4)
Solve for x.
In order to solve for x, we first need to distribute 4 and 3to each value inside their corresponding parenthesis.
2x + 4(2x + 7) = 3(2x+ 4)
2x + 8x + 28 = 6x + 12
10x + 28 = 6x + 12
Transpose 28 and 6x on the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
10x - 6x = 12 -28
4x = -16
Divide both sides by 4 in order to cancel out 4x, leaving behind x.
4x/4 = -16/4
x = -4
Final answer:
x = -4
