2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
10x and 6y are terms of an algebraic expression
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
-31 - 10x = 41 - 4x In algebra what you do to one side of the equation you do the the same as the other First add 31 to both sides -10x = 72 -4x then add 4x to both sides -6x = 72 divide both sides by -6 x = -12

10x=80 divide each side by 10 to get x by itself 10/10x=1x 80/10=8 x=8
12x-3=2x+17 10x-3=17 10x=20 x=2
10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3
Y = 10x 10x = 40 y = 40
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
10x 2x divide 2x equals?
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10

10x and 6y are terms of an algebraic expression
10x = 9x -25 10x -9x = -25 x = -25
10x + 3 = 15 10x = 15 - 3 10x = 12 x = 1.2
