If the solution of equation 3x-13y = - 12 is also the solution of equation x-3y = 4, then x =, y=

If the solution of equation 3x-13y = - 12 is also the solution of equation x-3y = 4, then x =, y=

It is known from the title that X and y are the solutions of the system of linear equations of two variables
3x-13y= -12 （1）
x-3y=4 （2）
(2) X 3 - (1)
4y=24
The solution is y = 6
Substituting y = 6 into (2), we get
x＝4＋3×6＝22
So, x = 22, y = 6

3x - (x + 30) = 0 to solve the equation

3x-(x+30)=0
3x-x-30=0
2x-30=0
2x=30
x=15

X + 2 / 3x + 2 / 3x + X + 30 = 180

x+2/3x+2/3x+x+30=180
2x +4/3x=180-30
10/3x=150
x=45
