5x+y=4,x-2y=3

Solution

5 x + y = 4, x - 2 y = 3

Solution

x = 1, y = - 1

Solution steps

[5 x + y = 4 x - 2 y = 3]

Isolate

x

for

5 x + y = 4 : x = \frac{4 - y}{5}

Substitute

x = \frac{4 - y}{5}

[\frac{4 - y}{5} - 2 y = 3]

Simplify

[\frac{4 - 11 y}{5} = 3]

Isolate

y

for

\frac{4 - 11 y}{5} = 3 : y = - 1

For

x = \frac{4 - y}{5}

Substitute

y = - 1

x = \frac{4 - ( - 1 )}{5}

\frac{4 - ( - 1 )}{5} = 1

x = 1

The solutions to the system of equations are:

x = 1, y = - 1
