Question

-4x + 3 (2x - 5) = 31

Please help & explain how you got to the answer

Answer 1

-4x + 3(2x - 5) = 31          (use distributive property to remove parentheses)
-4x + 6x - 15 = 31            (combine like terms)
2x - 15 = 31                    (add 15 to both sides)
     +15    +15
2x = 46                          (divide both sides by 2)
x = 23
