Solving the equation: x = 2 times [. 25 (X-10) - 10] just now you miscalculated, x = 30, I only know the solution of the equation,

Solving the equation: x = 2 times [. 25 (X-10) - 10] just now you miscalculated, x = 30, I only know the solution of the equation,

X = 2 times [1.25 (X-10) - 10]
x=2.5(x-10)-20
x=2.5x-25-20
2.5x-x=25+20
1.5x=45
x=45÷1.5
x=30

How to solve the equation (48 + x) multiplied by 10 = 1000

（48+x）×10=1000
48+x=100
x=100-48
x=52

How to solve the equation 20 * 10% + 30% X / x + 20 = 22%

20 * 10% + 30% X / x + 20 = 22%
20(0.1)+(x+20)/(0.3x) = 0.22
2 + 10(x+20)/(3x) = 0.22
6x + 10(x+20) = 0.66x
15.34x= -200
1534 x = -20000
x = -10000/767
