4x+3y=8,2x+y=2

Solution

4 x + 3 y = 8, 2 x + y = 2

Solution

x = - 1, y = 4

Solution steps

[4 x + 3 y = 8 2 x + y = 2]

Isolate

x

for

4 x + 3 y = 8 : x = \frac{8 - 3 y}{4}

Substitute

x = \frac{8 - 3 y}{4}

[2 \cdot \frac{8 - 3 y}{4} + y = 2]

Simplify

[\frac{8 - y}{2} = 2]

Isolate

y

for

\frac{8 - y}{2} = 2 : y = 4

For

x = \frac{8 - 3 y}{4}

Substitute

y = 4

x = \frac{8 - 3 \cdot 4}{4}

\frac{8 - 3 \cdot 4}{4} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 4
