How do i solve this equation: 15-g=23-2g

You would move the variables to one side and numbers to the other, so move - 2g to the other side to make it positive. That leaves you with g+15=23. Now move 15 to the other side which means it will be negative so subtract 15 from 23 which gives you 8. g = 8

So first add the g to the - 2g so now it is 15=23-g. Then subtract the 23 to the 15. - 8=-g so now just divide the negative and the final answer is 8=g
