Answer: The answer is x = 7/3
Step-by-step explanation: You start by solving the variable in brackets on the left side of the equation
4(2x - 1) - 7 = 4 - x + 6
(8x - 4) - 7 = 4 - x + 6
8x - 4 - 7 = 4 - x + 6
At this point, you collect like terms by bringing the unknown variables to the left side of the equation and the known variables to the right side of the equation
However, you must remember that each sign changes to the opposite as it crosses from one side of the equation to the other side (for example, + becomes - and, - becomes +). Therefore the equation can be re-written as;
8x + x = 4 + 6 + 4 + 7
9x = 21
Divide both sides of the equation by 9
x = 21/9
x = 7/3 (or 2 1/3)
