Answer:

x = 4

Step-by-step explanation:

After you simplify the left side by eliminating parentheses and collecting terms, you have a 2-step linear equation.

-3(4x +3) +4(6x +1) = 43 . . . . . . given

-12x -9 +24x +4 = 43 . . . . . eliminate parentheses

12x-5 = 43 . . . . . . . . . . . collect terms (now a 2-step equation)

12x = 48 . . . . . . . . . . step 1, add the opposite of the unwanted constant

x = 4 . . . . . . . . . . . step 2, divide by the coefficient of x

The solution is x = 4.

<em>Check</em>

-3(4·4 +3) +4(6·4 +1) = 43 . . . . substitute for x

-3(16 +3) +4(24 +1) = 43

-3(19) +4(25) = 43

-57 +100 = 43 . . . . . true
