Question

Solve for y in the equation!

Answer 1

In this equation, y equals 40

Explanation:

The equation is set out as 28- 0.3y = 0.7y- 12.

The first step is to undo the negative 12 at the end.

Then simplify to 40-0.3y=0.7y.

Now, add 0.3y to both sides to negate the negative 0.3y on the left side of the equation.

You are then left with 40=y or y=40, however you decide to write it

Answer 2

28 - 0.3y = 0.7y - 12 // add 12 to both sides
40 - 0.3y = 0.7y // add 0.3y to both sides
40 = 1y // divide both sides by 1
40 = y

the answer is 40
