4x-3y=-10,6x+9y=12

Solution

4 x - 3 y = - 10, 6 x + 9 y = 12

Solution

x = - 1, y = 2

Solution steps

[4 x - 3 y = - 10 6 x + 9 y = 12]

Isolate

x

for

4 x - 3 y = - 10 : x = \frac{- 10 + 3 y}{4}

Substitute

x = \frac{- 10 + 3 y}{4}

[6 \cdot \frac{- 10 + 3 y}{4} + 9 y = 12]

Simplify

[\frac{27 y - 30}{2} = 12]

Isolate

y

for

\frac{27 y - 30}{2} = 12 : y = 2

For

x = \frac{- 10 + 3 y}{4}

Substitute

y = 2

x = \frac{- 10 + 3 \cdot 2}{4}

\frac{- 10 + 3 \cdot 2}{4} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 2
