7x = 21 x = 3
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
5x + x - 6x + 2x = 2x
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
-5x+3(x+8)=16-2x
What is the answer to 2x - 5x plus 6.3 equals -14.4?
7x = 21 x = 3
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
5x + x - 6x + 2x = 2x
2x + 2 + 5x = 23 2x +5x = 23 -2 7x = 21 X = 3
8x-7 plus 2x equals 6 plus 5x plus 2?
2x+3x = 5x

How do you add 2x plus 3y equals 18 in 5x-y equals 11
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
-5x+3(x+8)=16-2x
