8x=7x-7 x=-7
x=(-9/7) 7x+12=3 7x=(-9) x=(-9/7)
7x+7=28x 28x-7x=7 21x=7 x=3
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

None. 7x - 1 is not equal to 7x - 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
7x + 29 = 36 7x + 29 - 29 = 36 - 29 7x = 7 7x/7 = 7/7 x = 1

7 equals 7, in any form of math. If it were to have something attached to it, however, such as 7x, it would most likely be something else.
-7 x -2= 14 24 - 9= 15 So no, it is not equal.
7
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
7x + y = 6 y = 6 - 7x dy/dx = 0-7 = -7 Slope = -7
