3x-y=20,6x+3y=60

Solution

3 x - y = 20, 6 x + 3 y = 60

Solution

x = 8, y = 4

Solution steps

[3 x - y = 20 6 x + 3 y = 60]

Isolate

x

for

3 x - y = 20 : x = \frac{20 + y}{3}

Substitute

x = \frac{20 + y}{3}

[6 \cdot \frac{20 + y}{3} + 3 y = 60]

Simplify

[5 y + 40 = 60]

Isolate

y

for

5 y + 40 = 60 : y = 4

For

x = \frac{20 + y}{3}

Substitute

y = 4

x = \frac{20 + 4}{3}

\frac{20 + 4}{3} = 8

x = 8

The solutions to the system of equations are:

x = 8, y = 4
