2x+7y-3=5,x+5y+6=0

2 x + 7 y - 3 = 5, x + 5 y + 6 = 0

x = \frac{82}{3}, y = - \frac{20}{3}

Solution steps

[2 x + 7 y - 3 = 5 x + 5 y + 6 = 0]

Isolate

x

for

2 x + 7 y - 3 = 5 : x = \frac{- 7 y + 8}{2}

Substitute

x = \frac{- 7 y + 8}{2}

[\frac{- 7 y + 8}{2} + 5 y + 6 = 0]

Simplify

[\frac{3 y + 8}{2} + 6 = 0]

Isolate

y

for

\frac{3 y + 8}{2} + 6 = 0 : y = - \frac{20}{3}

For

x = \frac{- 7 y + 8}{2}

Substitute

y = - \frac{20}{3}

x = \frac{- 7 ( - \frac{20}{3} ) + 8}{2}

\frac{- 7 ( - \frac{20}{3} ) + 8}{2} = \frac{82}{3}

x = \frac{82}{3}

The solutions to the system of equations are:

x = \frac{82}{3}, y = - \frac{20}{3}

2 x + 3 y = 4, 2 x - 4 y = 2

3 x - 2 y = 30, 2 x + 2 y = 70

x + 2 y = 0, - x + 2 y = 4

2 x + 3 y = 19, 2 x + y = 9

c = 19, a = 8, b = 9
