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

Solution

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

Solution

x = 4, y = 3

Solution steps

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

Isolate

x

for

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

Substitute

x = 10 - 2 y

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

Simplify

[20 - 5 y = 5]

Isolate

y

for

20 - 5 y = 5 : y = 3

For

x = 10 - 2 y

Substitute

y = 3

x = 10 - 2 \cdot 3

Simplify

x = 4

The solutions to the system of equations are:

x = 4, y = 3
