Solve the equation.
nadya68 [22]

Answer:

A. No solution

Step-by-step explanation:

The given equation is 4(2 x + 9) = 4(2 x +6)

We divide through by 4 to get:

2 x + 9 = 2 x +6

We now group similar terms to obtain:

2x - 2x = 6 - 9

0 =  - 3

This final statement is false.

Therefore the given equation has no solution.
