Question

8x-18=30

what is the answer

Answer 1

6.

Explanation:

The best way to solve this, is to work backwards. When subtracting, add on both sides

8x-18(+18)=30(+18)

8x=48

Now that we're multiplying, instead we divide both sides.

8x(/8)=48(/8)

x = 6

Answer 2

8x-18=30

First add the 18 to both sides

8x=48

Then divide the 8 into 48

Answer: 6
