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

Solution

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

Solution

x = 2, y = 4

Solution steps

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

Isolate

x

for

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

Substitute

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

[2 (- \frac{2 - 2 y}{3}) - 2 y = - 4]

Simplify

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

Isolate

y

for

\frac{- 4 - 2 y}{3} = - 4 : y = 4

For

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

Substitute

y = 4

x = - \frac{2 - 2 \cdot 4}{3}

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

x = 2

The solutions to the system of equations are:

x = 2, y = 4

7 m + 10 n = 77, 3 m + 4 n = 32

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

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

x = 4, y = 3
