-4x+3y=-4,-8x+5y=0

- 4 x + 3 y = - 4, - 8 x + 5 y = 0

x = - 5, y = - 8

Solution steps

[- 4 x + 3 y = - 4 - 8 x + 5 y = 0]

Isolate

x

for

- 4 x + 3 y = - 4 : x = - \frac{- 4 - 3 y}{4}

Substitute

x = - \frac{- 4 - 3 y}{4}

[- 8 (- \frac{- 4 - 3 y}{4}) + 5 y = 0]

Simplify

[- y - 8 = 0]

Isolate

y

for

- y - 8 = 0 : y = - 8

For

x = - \frac{- 4 - 3 y}{4}

Substitute

y = - 8

x = - \frac{- 4 - 3 ( - 8 )}{4}

- \frac{- 4 - 3 ( - 8 )}{4} = - 5

x = - 5

The solutions to the system of equations are:

x = - 5, y = - 8

x + y = 60, 16 x + 20 y = 1100

- 2 x + y = - 4, 2 x - 3 y = 8

x + 16 - 3 x + 8 y = 23, y = 4

5 x - 21 = 8 y, - 5 y + 10 x = 15

x - 5 y = 11, 2 x + 34 = 0
