3x+2y=51,2x+8y=18

3 x + 2 y = 51, 2 x + 8 y = 18

x = \frac{93}{5}, y = - \frac{12}{5}

Solution steps

[3 x + 2 y = 51 2 x + 8 y = 18]

Isolate

x

for

3 x + 2 y = 51 : x = \frac{51 - 2 y}{3}

Substitute

x = \frac{51 - 2 y}{3}

[2 \cdot \frac{51 - 2 y}{3} + 8 y = 18]

Simplify

[\frac{102 + 20 y}{3} = 18]

Isolate

y

for

\frac{102 + 20 y}{3} = 18 : y = - \frac{12}{5}

For

x = \frac{51 - 2 y}{3}

Substitute

y = - \frac{12}{5}

x = \frac{51 - 2 ( - \frac{12}{5} )}{3}

\frac{51 - 2 ( - \frac{12}{5} )}{3} = \frac{93}{5}

x = \frac{93}{5}

The solutions to the system of equations are:

x = \frac{93}{5}, y = - \frac{12}{5}

a + b = 7, 2 b + c = 90, c + a = 82

x + 12 y = 58, 5 x - 8 y = 18

2 x + y = 40, 3 x - y = 6

p = (3), q = (2)

7 x - 2 y = 20, x + 3 y = 16
