Question

How many solutions does the following equation have?

7x−(x−4)=6x−7
A.There is no way to determine the answer to this equation.
B. An infinite number of solutions will solve this equation.
C.There is only one real solution for the equation.
D.There is no real solution for this equation.

Answer 1

12x-11

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

7x- (x-4)= 6x -7

12x

7x- (x-4)= 6x -7

-11

12x-11
