8x-3y=18,-2x+9y=12

Solution

8 x - 3 y = 18, - 2 x + 9 y = 12

Solution

x = 3, y = 2

Solution steps

[8 x - 3 y = 18 - 2 x + 9 y = 12]

Isolate

x

for

8 x - 3 y = 18 : x = \frac{18 + 3 y}{8}

Substitute

x = \frac{18 + 3 y}{8}

[- 2 \cdot \frac{18 + 3 y}{8} + 9 y = 12]

Simplify

[\frac{- 18 + 33 y}{4} = 12]

Isolate

y

for

\frac{- 18 + 33 y}{4} = 12 : y = 2

For

x = \frac{18 + 3 y}{8}

Substitute

y = 2

x = \frac{18 + 3 \cdot 2}{8}

\frac{18 + 3 \cdot 2}{8} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 2
