Question

0.5 + 0.3y = 0.7y - 0.3
What’s the answer and the steps?

Answer 1

y = 2

Explanation:

1) 0.5 + 0.3y = 0.7y - 0.3 given

2) -0.5 = - 0.5 subtract on both sides to isolate the variable (y)

3) 0.3y = 0.7y - 0.8 Subtract again to isolate the variable (y)

- 0.7y -0.7y

4) -0.4y = -0.8 divide

-0.4y/ -0.4y

-0.8y/ -0.4y y = 2

Answer 2

Explanation:

0.5+0.3y=0.7y-0.3

You collection the like terms which looks likes

0.5+0.3=0.7y-0.3y

0.8y=0.5

Then you simplify, you gotta use a calculator tho

0.8y/0.8= 0.5/0.8

y=1.6
