16x - 10x + 9 = 99 - 30 6x + 9 = 69 so 6x = 60 or x = 10
2x-3 = 10x-99 start by moving the terms with variables (x) on one side of the equal sign, and the constants (regular number, with no variables) to the other side. Do this by addition and subtraction. 2x-3 = 10x-99 +99 +99 now you have 2x +96= 10x now get both of the variables on the right side 2x+96 = 10x -2x -2x now you have 96 = 8x now solve for x by dividing each side by 8 96/8 = 8x/8 x= 12

99 + 99 + 88 + 88 + 72 + 72 = 518
99
16x - 10x + 9 = 99 - 30 6x + 9 = 69 so 6x = 60 or x = 10
Simplifying we get 6x + 9 = 69 so x = 10
2x-3 = 10x-99 start by moving the terms with variables (x) on one side of the equal sign, and the constants (regular number, with no variables) to the other side. Do this by addition and subtraction. 2x-3 = 10x-99 +99 +99 now you have 2x +96= 10x now get both of the variables on the right side 2x+96 = 10x -2x -2x now you have 96 = 8x now solve for x by dividing each side by 8 96/8 = 8x/8 x= 12
12.99 + 99 + 99 + 99 = 309.99
199 + 199 + 199 + 199 + 99 + 99 + 99 = 1192

99 + 99 + 88 + 88 + 72 + 72 = 518
99 + 99 = 198
330 plus 99 plus 7 is equal to 436.
69 plus 54 plus 99 plus 62 plus 69 plus 62 plus 34 plus 59 plus 74 plus 99 plus 78 equals 759
99 plus 99 equal 198.In a nother form (This is in when it is used in math class ECT.)99+99=198.
