4x+8=7 You minus 8 from each side 4x=-1 Divide -1 by 4x The answer is β 4 1 β or -.25 You leave the negative If there is only one negative number(-1 being the case here) then its negative If there are two negatives, its a positive If there are two positive numbers, its positive

To solve 4 x + 8 = 7 , subtract 8 from both sides to get 4 x = β 1 , then divide by 4 to find x = β 4 1 β . You retain the negative sign as itβs the result of dividing -1 by a positive number. Your answer is correct!
