18 -3.8x = 7.36 -1.9x --> put #'s with #'s, x's with x's

18 -7.36 = -1.9x +3.8x

10.64 = 1.9x

10.64/1.9 = x

5.6 = x

Combine like terms!

First step: Add 3.8x to both sides of the equation.

18 - 3.8x + 3.8x = 7.36 - 1.9x + 3.8x

The -3.8x and 3.8x cancel out. -1.9x + 3.8x = 1.9x

New equation: 18 = 7.36 + 1.9x

Second step: Subtract 7.36 from both sides of the equation.

18 - 7.36 = 7.36 - 7.36 +1.9x

The - and + 7.36 on the right cancel. 18 - 7.36 = 10.64

New equation: 10.64 = 1.9x

Third step: Divide both sides by 1.9

10.64/1.9 = 1.9x/1.9

1.9/1.9 = 1, and 1*x = x. 10.64/1.9 = 5.6

Therefore, x = 5.6

add 3.8x to -1.9 to get 1.9x

and then subtract 7.36 from 18 to get 10.64

then divide 10.64 by 1.9 (to isolate the x) to get 5.6

and then 5.6 equals x

:]

18-3.8x=7.36-1.9x

+3.8x=+3.8x

18=7.36+1.9x

-7.36=-7.36

10.64=1.9x

5.6=x

I hope that's right and I helped!!!

10.64 = 1.9x

x=5.6
