Question

find x. 0.3+0.7x=0.85x​

Answer 1

Answer:

0.3+0.7x=0.85x

We move all terms to the left:

0.3+0.7x-(0.85x)=0

We add all the numbers together, and all the variables

0.7x-(+0.85x)+0.3=0

We get rid of parentheses

0.7x-0.85x+0.3=0

We add all the numbers together, and all the variables

-0.15x+0.3=0

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

-0.15x=-0.3

x=-0.3/-0.15

x=2
