@Batmantallk @StudySpark24 If we take 5 to the ryt side, it bcmz -5 so if we subtract 5 from 12 we get 7. Nw tht we've a 7 on the ryt and an x in a square root on the left, we then square both sides to get rid of the square root. So we're left with only x on the left and 7ยฒ on the ryt so the answr is 49.
