8x - 2 = -9 + 7x subtract 7x to both sides 8x  - 2 - 7x = -9 +7x -7x simplify x -2 = -9 now, add 2 to both sides x -2 + 2= -9 + 2 simplify x = -7 BTW, You got #5 wrong 4m - 4 = 4m subtract both sides to 4m 4m - 4 -4m = 4m -4m simplify -4 = 0 ....-4 can not equal 0 so answer on this one is No Solution
