The question contains an expression but not an equation. You cannot solve an expression.
7-5x=10-(6x+7) 7-5x=-60x-70 +5x +5x 7=-55x-70 +70 +70 77=-55x Divide -55 -1.4 = x
There's nothing to solve, it's simply an expression.
x = 25 / 3squared + 5
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
2x squared minus 5x minus 3 factored is (2x+1)(x-3).

-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
cheater == 2[x-3]+3[x-2]=18 2x-6+3x-6=18 5x-12=18 5x=30 x=30/5=6
7-5x=10-(6x+7) 7-5x=-60x-70 +5x +5x 7=-55x-70 +70 +70 77=-55x Divide -55 -1.4 = x

3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
x = 25 / 3squared + 5
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
you use the quadratic formula: x= -b plus/minus the square root of b^2 - 4ac all over 2a. use this site to help you out: wolframalpha.com
