Solve 15 - w/4 = 28. If an explanation is possible, definitely include one, so i could figure out similar equations like this one.

15 - w/4 = 28.

Our goal is to find the variable by itself.

First, reverse the equation to cancel itself out.

Use the Multiplication and Addition Property of Equality.

So do +15 to cancel 15 out.

Add the 15 to 28, which equals 43.

Do x4, to cancel 4 out.

43 x 4 = 172.

w will equal 172.

15 - 172/4 = 28.

First try and make w the subject of the formula which is by collecting like terms

-w/4=28-15 (15 becomes - because it has been moved or the equality sign)

-w/4=13

then you cross multiply

which will be 52 = w

therefore w= 52
