x+2y=10,4x-2y=5

Solution

x + 2 y = 10, 4 x - 2 y = 5

Solution

x = 3, y = \frac{7}{2}

Solution steps

[x + 2 y = 10 4 x - 2 y = 5]

Isolate

x

for

x + 2 y = 10 : x = 10 - 2 y

Substitute

x = 10 - 2 y

[4 (10 - 2 y) - 2 y = 5]

Simplify

[40 - 10 y = 5]

Isolate

y

for

40 - 10 y = 5 : y = \frac{7}{2}

For

x = 10 - 2 y

Substitute

y = \frac{7}{2}

x = 10 - 2 \cdot \frac{7}{2}

10 - 2 \cdot \frac{7}{2} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = \frac{7}{2}
