Answer:
12x-11
Step-by-step explanation:
There is no known solution, but this can be simplified. Add up all of the coefficients(# connected by the variable). Since after 7x is a - , the x following has to be negative. After adding the coefficients, you should have below, 12x. Then, you add up all of your constants.(# w/ no variable). Adding negative and positive, you should get below, -11. Finally, you should of simplified your equation to 12x-11.
Equation:
7x- (x-4)= 6x -7
<u>7x- (x</u>-4)= <u>6x</u> -7
12x
7x- (x-<u>4</u>)= 6x <u>-7</u>
-11
12x-11
