8x - 2y = 48 equals
x = 7.
First, make sure to add in your 4 in replace of the y. Multiply 2 x 4 to get 8. Your problem should look like: 8x - 8 = 48.
Second, add 8 to both sides. Your problem should look like: 8x = 48 + 8.
Third, add 48 + 8 to get 56. Your problem should look like: 8x = 56.
Fourth, divide both sides by 8. Your problem should look like: x =

.
Fifth,simplify

to get 7. Your problem should look like: x = 7, which is your answer.
