Fill in the blanks with the correct words:

an contain a variable ( must or may)

the equation y-4=1 has ( or many)

The answer to your question is: x = -10

Step-by-step explanation:

                                            2(3x - 8) = 8x + 4

 Expanding                         6x - 16 = 8x + 4

                                            6x - 8x = 4 + 16

Simplifying                        -2x = 20

                                             x = 20 / -2

Result                                   x = -10
