2x-2=10x + 20

How do I solve for x

Answer: x = - 11/4 as a proper fraction; - 2.75 as a decimal.

Step-by-step explanation:

2x-2 = 10x + 20

Combine like terms

-2-20=10*-2*

-22=-8*

Divide both sides by 8

x=-22/8

=-11/4 or 2 3/4

X = - 2.75

Plug the value of x into the equation:

2 (-2.75) - 2 = 10 (-2.75) + 20

-5.5 - 2 = - 27.5 + 20

-7.5 = - 7.5

16

Step-by-step explanation:

2x - 2 = 10 + 20

2x - 2 + 2 = 10 + 20 + 2

2x = 32

x = 32/2 = 16

Plug this in, too.

2 (16) - 2 = 10 + 20

30 = 30 and they are equal!
