2x+5y=5,-3x+7y=36

Solution

2 x + 5 y = 5, - 3 x + 7 y = 36

Solution

x = - 5, y = 3

Solution steps

[2 x + 5 y = 5 - 3 x + 7 y = 36]

Isolate

x

for

2 x + 5 y = 5 : x = \frac{5 - 5 y}{2}

Substitute

x = \frac{5 - 5 y}{2}

[- 3 \cdot \frac{5 - 5 y}{2} + 7 y = 36]

Simplify

[\frac{- 15 + 29 y}{2} = 36]

Isolate

y

for

\frac{- 15 + 29 y}{2} = 36 : y = 3

For

x = \frac{5 - 5 y}{2}

Substitute

y = 3

x = \frac{5 - 5 \cdot 3}{2}

\frac{5 - 5 \cdot 3}{2} = - 5

x = - 5

The solutions to the system of equations are:

x = - 5, y = 3
