5y+3x=7,4x-2y=-8

Solution

5 y + 3 x = 7, 4 x - 2 y = - 8

Solution

x = - 1, y = 2

Solution steps

[5 y + 3 x = 7 4 x - 2 y = - 8]

Isolate

y

for

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

Substitute

y = \frac{7 - 3 x}{5}

[4 x - 2 \cdot \frac{7 - 3 x}{5} = - 8]

Simplify

[\frac{- 14 + 26 x}{5} = - 8]

Isolate

x

for

\frac{- 14 + 26 x}{5} = - 8 : x = - 1

For

y = \frac{7 - 3 x}{5}

Substitute

x = - 1

y = \frac{7 - 3 ( - 1 )}{5}

\frac{7 - 3 ( - 1 )}{5} = 2

y = 2

The solutions to the system of equations are:

x = - 1, y = 2

Popular Examples

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

4x+3y=-2.5,5x+2y=10

4 x + 3 y = - 2.5, 5 x + 2 y = 10

17x+10y=61,5x+10y=4

17 x + 10 y = 61, 5 x + 10 y = 4

2x+y+z=7,x-y-z=-4,3x+2y+z=10

2 x + y + z = 7, x - y - z = - 4, 3 x + 2 y + z = 10

2x+y=-4,5x-3y=1

2 x + y = - 4, 5 x - 3 y = 1
