7x+2y=3,3x+5y=22

Solution

7 x + 2 y = 3, 3 x + 5 y = 22

Solution

x = - 1, y = 5

Solution steps

[7 x + 2 y = 3 3 x + 5 y = 22]

Isolate

x

for

7 x + 2 y = 3 : x = \frac{3 - 2 y}{7}

Substitute

x = \frac{3 - 2 y}{7}

[3 \cdot \frac{3 - 2 y}{7} + 5 y = 22]

Simplify

[\frac{9 + 29 y}{7} = 22]

Isolate

y

for

\frac{9 + 29 y}{7} = 22 : y = 5

For

x = \frac{3 - 2 y}{7}

Substitute

y = 5

x = \frac{3 - 2 \cdot 5}{7}

\frac{3 - 2 \cdot 5}{7} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 5
