Answer:
x = 4
Stepbystep explanation:
After you simplify the left side by eliminating parentheses and collecting terms, you have a 2step linear equation.
3(4x +3) +4(6x +1) = 43 . . . . . . given
12x 9 +24x +4 = 43 . . . . . eliminate parentheses
12x5 = 43 . . . . . . . . . . . collect terms (now a 2step 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.

Check
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
