5x-y=3,2x+4y=-12

Solution

5 x - y = 3, 2 x + 4 y = - 12

Solution

x = 0, y = - 3

Solution steps

[5 x - y = 3 2 x + 4 y = - 12]

Isolate

x

for

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

Substitute

x = \frac{3 + y}{5}

[2 \cdot \frac{3 + y}{5} + 4 y = - 12]

Simplify

[\frac{6 + 22 y}{5} = - 12]

Isolate

y

for

\frac{6 + 22 y}{5} = - 12 : y = - 3

For

x = \frac{3 + y}{5}

Substitute

y = - 3

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

Simplify

x = 0

The solutions to the system of equations are:

x = 0, y = - 3

2 x + 4 y - 2 = 4, x + 8 y - 10 = 0

3 x + 8 = 2, x - a = 0

3 b = 3, a = 1

6x-3y=-10,3x+5y-8=0

6 x - 3 y = - 10, 3 x + 5 y - 8 = 0

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