Solve for x.<br> 4(2x - 1) - 7 = 4 - x + 6
Akimi4 [234]
<span>The answer is that x = 21/9.

Start with the original:                  4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span>                   <span> 8x - 4 - 7 = 4 - x + 6.
Now combine the like terms.       8x - 11 = -x + 10.
Now add x to both sides.             9x - 11 = 10.
Now add 11 to both sides.            9x = 21.
And divide by 9 on both side.      x = 21/9. </span>
