2x+7y=-4,3x-4y=-6

Solution

2 x + 7 y = - 4, 3 x - 4 y = - 6

Solution

x = - 2, y = 0

Solution steps

[2 x + 7 y = - 4 3 x - 4 y = - 6]

Isolate

x

for

2 x + 7 y = - 4 : x = \frac{- 4 - 7 y}{2}

Substitute

x = \frac{- 4 - 7 y}{2}

[3 \cdot \frac{- 4 - 7 y}{2} - 4 y = - 6]

Simplify

[\frac{- 12 - 29 y}{2} = - 6]

Isolate

y

for

\frac{- 12 - 29 y}{2} = - 6 : y = 0

For

x = \frac{- 4 - 7 y}{2}

Substitute

y = 0

x = \frac{- 4 - 7 \cdot 0}{2}

\frac{- 4 - 7 \cdot 0}{2} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = 0

Popular Examples

2x+y=8,5x+2y=10

2 x + y = 8, 5 x + 2 y = 10

x+y=10,6x+5y=56

x + y = 10, 6 x + 5 y = 56

f (x) = 20, x + l = 20

2j+s=14,3s+j=270

2 j + s = 14, 3 s + j = 270

2x-5y=3,3x+2y=14

2 x - 5 y = 3, 3 x + 2 y = 14
