3x-4y=-6,2x+4y=16

Solution

3 x - 4 y = - 6, 2 x + 4 y = 16

Solution

x = 2, y = 3

Solution steps

[3 x - 4 y = - 6 2 x + 4 y = 16]

Isolate

x

for

3 x - 4 y = - 6 : x = \frac{- 6 + 4 y}{3}

Substitute

x = \frac{- 6 + 4 y}{3}

[2 \cdot \frac{- 6 + 4 y}{3} + 4 y = 16]

Simplify

[\frac{- 12 + 20 y}{3} = 16]

Isolate

y

for

\frac{- 12 + 20 y}{3} = 16 : y = 3

For

x = \frac{- 6 + 4 y}{3}

Substitute

y = 3

x = \frac{- 6 + 4 \cdot 3}{3}

\frac{- 6 + 4 \cdot 3}{3} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 3

Popular Examples

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

5x-2y=4,3x+4y=18

5 x - 2 y = 4, 3 x + 4 y = 18

7x-2y=9,4x+6y=15

7 x - 2 y = 9, 4 x + 6 y = 15

6x-5y=-9,4x+3y=13

6 x - 5 y = - 9, 4 x + 3 y = 13

x + y = 5, x - y = 7
