Question

Solve for the unknown, showing all work. (If necessary, round to the nearest hundredth.)

8A-40=4A + 60

Answer 1

A = 25

Explanation:

This is a simple rearranging question as there is only one unknown

8A - 40 = 4A + 60

first, we want all the letters As on one side and natural numbers on the other

add 40 to both sides:

8A = 4A + 60 + 40

Subtract 4A from both sides:

8A - 4A = 60 + 40

combine like terms:

4A = 100

divide both sides by 4:

A = 100 ÷ 4

A = 25

hope this helps :)
