5x-2y=1,2x+y=4

Solution

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

Solution

x = 1, y = 2

Solution steps

[5 x - 2 y = 1 2 x + y = 4]

Isolate

x

for

5 x - 2 y = 1 : x = \frac{1 + 2 y}{5}

Substitute

x = \frac{1 + 2 y}{5}

[2 \cdot \frac{1 + 2 y}{5} + y = 4]

Simplify

[\frac{2 + 9 y}{5} = 4]

Isolate

y

for

\frac{2 + 9 y}{5} = 4 : y = 2

For

x = \frac{1 + 2 y}{5}

Substitute

y = 2

x = \frac{1 + 2 \cdot 2}{5}

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 2
