-79 = 7x + 3(4x - 1) Help

Mathematics
1 answer:
Dmitry [639]3 years ago
7 0

Answer:

x = - 4

Step-by-step explanation:

-79 = 7x + 3(4x - 1)

-79 = 7x + 12x - 3                      Distribute 3 to the paranthesis

-79 = 19x - 3                              Add like terms

-76 = 19x                                   Add 3 to both sides

- 4 = x                                          Divide 19 to both sides
