Question

PLEASE HELP I DO NOT UNDERSTAND!

Answer 1

Answer:

1.) x = -3 2.) x = 4/3 3.) x = 698/77 or 9.1

Step-by-step explanation:

1.) 4 + 2x = -2

2x = -2 - 4

2x = -6

x = -3

2.) -1 (3x - 12) = 9x - 4

-(3x - 12) = 9x - 4

-3x + 12 = 9x - 4

-3x - 9x = -4 - 12

-12x = -16

x = 4/3

3.) x - 4 = 13 (6x - 54)

x - 4 = 78x - 702

x - 78x = -702 + 4

-77x = -698

x = 698/77 or 9.1

Answer 2

Answer:

1. x = -3

2. x = 4/3

3. x = 698/77

Step-by-step explanation:

4+2x=-2

-4       -4

2x= -6

/2     /2

x=-3

You have to get x alone on one side. Search up on yt "How to solve for x on two sides."
