3x+5y=15,2x-3y=-9

Solution

3 x + 5 y = 15, 2 x - 3 y = - 9

Solution

x = 0, y = 3

Solution steps

[3 x + 5 y = 15 2 x - 3 y = - 9]

Isolate

x

for

3 x + 5 y = 15 : x = \frac{15 - 5 y}{3}

Substitute

x = \frac{15 - 5 y}{3}

[2 \cdot \frac{15 - 5 y}{3} - 3 y = - 9]

Simplify

[\frac{30 - 19 y}{3} = - 9]

Isolate

y

for

\frac{30 - 19 y}{3} = - 9 : y = 3

For

x = \frac{15 - 5 y}{3}

Substitute

y = 3

x = \frac{15 - 5 \cdot 3}{3}

Simplify

x = 0

The solutions to the system of equations are:

x = 0, y = 3
