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

Solution

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

Solution

x = 1, y = 6

Solution steps

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

Isolate

x

for

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

Substitute

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

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

Simplify

[\frac{- 6 + 5 y}{3} = 8]

Isolate

y

for

\frac{- 6 + 5 y}{3} = 8 : y = 6

For

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

Substitute

y = 6

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

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 6

3 x + 5 y = 21, 4 x - 2 y = 2

x + y = 5, 3 x + y = 18

x+4y=-25,-10x-5y=5

x + 4 y = - 25, - 10 x - 5 y = 5

5x+7y=17,2x+y=5

5 x + 7 y = 17, 2 x + y = 5

12x-13y=9,-4x+17y=35

12 x - 13 y = 9, - 4 x + 17 y = 35
