2x+4y=22,2x+2y=15

Solution

2 x + 4 y = 22, 2 x + 2 y = 15

Solution

x = 4, y = \frac{7}{2}

Solution steps

[2 x + 4 y = 22 2 x + 2 y = 15]

Isolate

x

for

2 x + 4 y = 22 : x = 11 - 2 y

Substitute

x = 11 - 2 y

[2 (11 - 2 y) + 2 y = 15]

Simplify

[22 - 2 y = 15]

Isolate

y

for

22 - 2 y = 15 : y = \frac{7}{2}

For

x = 11 - 2 y

Substitute

y = \frac{7}{2}

x = 11 - 2 \cdot \frac{7}{2}

11 - 2 \cdot \frac{7}{2} = 4

x = 4

The solutions to the system of equations are:

x = 4, y = \frac{7}{2}
