Question

How do I solve 28-0.3y=0.7y-12

Answer 1

28-0.3y=0.7y-12 add 0.3y
+0.3y +0.3y
28=0.7y-12+0.3y
28=y-12 add 12
+12 +12
28+12=y
40=y
y=40 solved for y

Answer 2

The value of the equation is
`y=40`.

Explanation:

Consider the provided equation.

`28-0.3y=0.7y-12`

We need to solve the equation for y.

Add 0.3y to both sides of the equation.

`28-0.3y+0.3y=0.7y+0.3y-12`

`28=y-12`

Add 12 to both the sides of the equation.

`28+12=y-12+12`

`y=40`

Hence, the value of the equation is
`y=40`.
