Question

0.6x + 0.2x = 0.4x + 8​

Answer 1

Step-by-step explanation:

0.6x+0.2x=0.4x+8

We move all terms to the left:

0.6x+0.2x-(0.4x+8)=0

We add all the numbers together, and all the variables

0.8x-(0.4x+8)=0

We get rid of parentheses

0.8x-0.4x-8=0

We add all the numbers together, and all the variables

0.4x-8=0

We move all terms containing x to the left, all other terms to the right

0.4x=8

x=8/0.4

x=20
