4x-y=9,2x-3y=-23

Solution

4 x - y = 9, 2 x - 3 y = - 23

Solution

x = 5, y = 11

Solution steps

[4 x - y = 9 2 x - 3 y = - 23]

Isolate

x

for

4 x - y = 9 : x = \frac{9 + y}{4}

Substitute

x = \frac{9 + y}{4}

[2 \cdot \frac{9 + y}{4} - 3 y = - 23]

Simplify

[\frac{9 - 5 y}{2} = - 23]

Isolate

y

for

\frac{9 - 5 y}{2} = - 23 : y = 11

For

x = \frac{9 + y}{4}

Substitute

y = 11

x = \frac{9 + 11}{4}

\frac{9 + 11}{4} = 5

x = 5

The solutions to the system of equations are:

x = 5, y = 11

Popular Examples

2 x - y = 2, y - x = 2

4x-8y=-14,2x+4y=-7

4 x - 8 y = - 14, 2 x + 4 y = - 7

2 x + y = 1, 5 x - y = 12

3x+3y=6,3x+2y=4

3 x + 3 y = 6, 3 x + 2 y = 4

a+2b+3c=0,a+b=0,b+3c=0

a + 2 b + 3 c = 0, a + b = 0, b + 3 c = 0
