Someone please help me on this question ?:)

Answer 1

Answer:

x=-121

Step-by-step explanation:

.4(5+2x) -12 = .9x+2.1

Distribute the .4

2 + .8x -12 = .9x+2.1

Combine like terms

-10 +.8x = .9x +2.1

Subtract .8x from each side

-10 +.8x-.8x = .9x-.8x +2.1

-10 = .1x +2.1

Subtract 2.1 from each side

-10-2.1 = .1x +2.1-2.1

-12.1 = .1x

Divide by .1

-12.1/.1 = 1.x/.1

-121 =x
