How to solve the equation of 10x + 6 = 12x-6?

10x+6=12x-6
Displacement 10x-12x = - 6-6
-2x=-12
x=12/2
x=6

How to solve the equation of 10x-10 = 12x-80?

10x－10＝12x－80
12x-10x=80-10
2x=70
x=70÷2
x=35

Find the solution of 20x (x + 3) + 20x = 150

20x (x + 3) + 20x = 150 x ^ 2 represents the square of X
20X^2 + 60X + 20 X=150
20X^2 + 80X - 150=0
2X ^ 2 + 8x - 15 = 0 (eliminate 0, equal to divide by 10)
2（X^2 + 4X) - 15 = 0
2 [(X + 2)^2 -4] - 15 = 0
2 [(X + 2)^2]-23= 0
(X + 2)^2 = 23/2
X + 2 = +_ 23 / 2 under positive and negative root sign
X = the root of plus or minus 2, 46 - 2, because the mathematical symbol can't be displayed, so I expressed it in words,
