7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2
It is 9x
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
It is an equation and the value of x is 1
10x - 3 - 2x = 4 7x - 3 = 4 7x = 7 x = 1
7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2
It is 9x
7x=2x-4 5x=-4 x=-4/5
2x+3=9x 3=9x-2x 3=7x x=3/7
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
2x = 7x - 10 subtract the 7x from both sides 2x - 7x = -10 -5x = -10 divide both sides by -5 x = 2
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
7x-1=2x+5 7x-2x=5+1 5x=6 x=6/5=1.2
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
It is an equation and the value of x is 1
65 = 2x - 7x 65 = -5x 65/-5 = -5x/-5 -13 = x
