8x-5y+40=7,x-2y=0

Solution

8 x - 5 y + 40 = 7, x - 2 y = 0

Solution

x = - 6, y = - 3

Solution steps

[8 x - 5 y + 40 = 7 x - 2 y = 0]

Isolate

x

for

8 x - 5 y + 40 = 7 : x = \frac{5 y - 33}{8}

Substitute

x = \frac{5 y - 33}{8}

[\frac{5 y - 33}{8} - 2 y = 0]

Simplify

[\frac{- 11 y - 33}{8} = 0]

Isolate

y

for

\frac{- 11 y - 33}{8} = 0 : y = - 3

For

x = \frac{5 y - 33}{8}

Substitute

y = - 3

x = \frac{5 ( - 3 ) - 33}{8}

\frac{5 ( - 3 ) - 33}{8} = - 6

x = - 6

The solutions to the system of equations are:

x = - 6, y = - 3

Popular Examples

7/x-(15)/y =9,*(11)/x-8/y =-17

\frac{7}{x} - \frac{15}{y} = 9, \cdot \frac{11}{x} - \frac{8}{y} = - 17

5x-2y=7,4x+3y=-2

5 x - 2 y = 7, 4 x + 3 y = - 2

3x-18y=-54,5x-4y=-40

3 x - 18 y = - 54, 5 x - 4 y = - 40

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

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

x+y=3,2x+5y=15,2x+2y=-3

x + y = 3, 2 x + 5 y = 15, 2 x + 2 y = - 3
