3x out of 4-11x4 out of 20 = 2 solution equation

3x out of 4-11x4 out of 20 = 2 solution equation


3 / 4x-11 / 20x4 = 2 times 20
15x-44=40
15x=44+40
15x=84
x=5.6



Solution equation: - 3x = - 20


X = - 20 / (Division) - 3
X = 20 / 3 (negative leads to positive)



(X-10) x9 / 20 = 2 / 3x-50 + 10 to solve the equation


Hello, Qin Tu
(x-10)×(9/20)=(2/3)x-50+10
(9/20)x-9/2=(2/3)x-40
(2/3)x-(9/20)x=40-9/2
(13/60)x=71/2
x=(71/2)÷(13/60)
x=2130/13



(x = 120) / 20 = 3x to solve the equation


You write the wrong question, x = 120, what equation do you ask people to seek



X + 3 / 10 x = 20 to solve the equation


(1+3/10)X=20
13/10 X=20
X=20*10/13
X=200/13



What is the solution of equation 3x + 2 = 0?


-2/3



The solution of equation 3x + 2 = 0 is X=


Minus two thirds



The solution of equation 3x + | x | + 4 = 0 is


It is easy to know x from the title



If x = - 9 is the solution of equation 1 / 3x + M = - 1, then M = ()


m=2



If x = 1 is the solution of the equation m (x-1) = 3x-9, then M = what


Substituting x = 1 into the original equation, m (1-1) = 3 * 1-9, that is, 0 = - 6, so the equation does not hold. We can do this, because m (x-1) = 3x-9, mx-m = 3x-9, M = (3x-9) / (x-1), we can see that x can not be equal to 1. If x = 1, then the denominator X-1 = 0, that is to say, the equation is meaningless or the formula is infinite
