2x-7y=7,3x+y=22

Solution

2 x - 7 y = 7, 3 x + y = 22

Solution

x = 7, y = 1

Solution steps

[2 x - 7 y = 7 3 x + y = 22]

Isolate

x

for

2 x - 7 y = 7 : x = \frac{7 + 7 y}{2}

Substitute

x = \frac{7 + 7 y}{2}

[3 \cdot \frac{7 + 7 y}{2} + y = 22]

Simplify

[\frac{21 + 23 y}{2} = 22]

Isolate

y

for

\frac{21 + 23 y}{2} = 22 : y = 1

For

x = \frac{7 + 7 y}{2}

Substitute

y = 1

x = \frac{7 + 7 \cdot 1}{2}

\frac{7 + 7 \cdot 1}{2} = 7

x = 7

The solutions to the system of equations are:

x = 7, y = 1

Popular Examples

5 b = 5, a = 12

y = 16, x = 2

v=3i+2j+k,w=3i+4k

v = 3 i + 2 j + k, w = 3 i + 4 k

x + y = 1, 4 x - y = 4

x + y = 1, 4 x - y = 2
