3x+5y=8,2x-4y=-2

Solution

3 x + 5 y = 8, 2 x - 4 y = - 2

Solution

x = 1, y = 1

Solution steps

[3 x + 5 y = 8 2 x - 4 y = - 2]

Isolate

x

for

3 x + 5 y = 8 : x = \frac{8 - 5 y}{3}

Substitute

x = \frac{8 - 5 y}{3}

[2 \cdot \frac{8 - 5 y}{3} - 4 y = - 2]

Simplify

[\frac{16 - 22 y}{3} = - 2]

Isolate

y

for

\frac{16 - 22 y}{3} = - 2 : y = 1

For

x = \frac{8 - 5 y}{3}

Substitute

y = 1

x = \frac{8 - 5 \cdot 1}{3}

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 1
