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

Solution

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

Solution

x = 2, y = 4

Solution steps

[3 x - y - 2 = 0 2 x + y = 8]

Isolate

x

for

3 x - y - 2 = 0 : x = \frac{y + 2}{3}

Substitute

x = \frac{y + 2}{3}

[2 \cdot \frac{y + 2}{3} + y = 8]

Simplify

[\frac{5 y + 4}{3} = 8]

Isolate

y

for

\frac{5 y + 4}{3} = 8 : y = 4

For

x = \frac{y + 2}{3}

Substitute

y = 4

x = \frac{4 + 2}{3}

\frac{4 + 2}{3} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 4

Popular Examples

4x+5y=5,7x-2y=41

4 x + 5 y = 5, 7 x - 2 y = 41

5x+3y=1,4x-2y=8

5 x + 3 y = 1, 4 x - 2 y = 8

x/5-y/4 =0,3x+y/2 =17

\frac{x}{5} - \frac{y}{4} = 0, 3 x + \frac{y}{2} = 17

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

3-x/8 =5, x/8 =5 x/2-2/3 (x-4)+5

3 - \frac{x}{8} = 5, \frac{x}{8} = 5 \frac{x}{2} - \frac{2}{3} (x - 4) + 5
