text: solve the following equations for the unknown.? (a) 1/3x+1=-7  (b) x-3/3-4=x-2 the grouping of terms here is ambiguous. i added parentheses to show the grouping i assumed.  (a) (1/3)x + 1 = -7 (1/3)x = -8 x = -3 x 8 = -24 x = -24  (b) [(x-3)/3] - 4 = x - 2  (x-3)/3 = x + 2 x-3 = 3x + 6 2x = -9 x = -9/2 = -4.5 x = -4.5
