X/7 = 6
multiply both sides by 7/1
(7/1)(X/7) = (6)(7/1)
7 cancels on left
X = 42
----------------check in original equation
42/7 = 6
6 = 6
----------checks
7/2x = 3 Multiply both sides by 2x: 7 = 3*2x = 6x Divide both sides by 6 = 7/6 = x ie x = 1.1666...
7x-6=20 You add 6 to both sides of the equal sign to get 7x=26. Then you divide both sides by 7 to isolate "x". x=26/7
5.5 x 6 x 7 = 231
8x + 7 = 55 Subtract 7 from both sides: 8x = 48 Divide both sides by 8: x = 6
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
7x = 42 Divide both sides by '7'. Hence x = 42/7 x = 6 The answer!!!!!
48
7/2x = 3 Multiply both sides by 2x: 7 = 3*2x = 6x Divide both sides by 6 = 7/6 = x ie x = 1.1666...
3x + 6 = 27.Subtract 6 from both sides: 3x = 27 - 6 = 21.Divide both sides by 3: x = 21/3 = 7.x = 7
7x-6=20 You add 6 to both sides of the equal sign to get 7x=26. Then you divide both sides by 7 to isolate "x". x=26/7
5.5 x 6 x 7 = 231
8x + 7 = 55 Subtract 7 from both sides: 8x = 48 Divide both sides by 8: x = 6
8
Let the variable be x: 12/x = 6/7 Multiply both sides by x: 12 = 6x/7 Multiply both sides by 7: 84 = 6x Divide both sides by 6 to find the value of x: x = 14
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
3x+7=15 -7 -7 3x=6 (Divide) 3 3 x=2 Check it: 3(2)+7=15 6+7=15 15=15 :D
4 x (7 - 10/10) = 4 x (7 - 1) = 4 x 6 = 24
