2x+y=31,3y-x=23

Solution

2 x + y = 31, 3 y - x = 23

Solution

x = 10, y = 11

Solution steps

[2 x + y = 31 3 y - x = 23]

Isolate

x

for

2 x + y = 31 : x = \frac{31 - y}{2}

Substitute

x = \frac{31 - y}{2}

[3 y - \frac{31 - y}{2} = 23]

Simplify

[\frac{- 31 + 7 y}{2} = 23]

Isolate

y

for

\frac{- 31 + 7 y}{2} = 23 : y = 11

For

x = \frac{31 - y}{2}

Substitute

y = 11

x = \frac{31 - 11}{2}

\frac{31 - 11}{2} = 10

x = 10

The solutions to the system of equations are:

x = 10, y = 11

Popular Examples

x+sqrt(y)=7,sqrt(x)+y=11

x + y = 7, x + y = 11

4x+6y=-1,10x+18y=14

4 x + 6 y = - 1, 10 x + 18 y = 14

-x+3y-13=0,-4x+2y-22=0

- x + 3 y - 13 = 0, - 4 x + 2 y - 22 = 0

x/(10)+y/5+1=1,5 x/8+y/6 =15

\frac{x}{10} + \frac{y}{5} + 1 = 1, 5 \frac{x}{8} + \frac{y}{6} = 15

(1) x = 7, 3 x + y = 25
