4x-7y=3,-2x-2y=-18

Solution

4 x - 7 y = 3, - 2 x - 2 y = - 18

Solution

x = 6, y = 3

Solution steps

[4 x - 7 y = 3 - 2 x - 2 y = - 18]

Isolate

x

for

4 x - 7 y = 3 : x = \frac{3 + 7 y}{4}

Substitute

x = \frac{3 + 7 y}{4}

[- 2 \cdot \frac{3 + 7 y}{4} - 2 y = - 18]

Simplify

[\frac{- 3 - 11 y}{2} = - 18]

Isolate

y

for

\frac{- 3 - 11 y}{2} = - 18 : y = 3

For

x = \frac{3 + 7 y}{4}

Substitute

y = 3

x = \frac{3 + 7 \cdot 3}{4}

\frac{3 + 7 \cdot 3}{4} = 6

x = 6

The solutions to the system of equations are:

x = 6, y = 3

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

-5x+y=6,5x-7y=18

- 5 x + y = 6, 5 x - 7 y = 18

72x+3y=6,3x-2y=7

72 x + 3 y = 6, 3 x - 2 y = 7

-7x+6y=-2,9x+3y=8

- 7 x + 6 y = - 2, 9 x + 3 y = 8

x - y = 2, 3 x + 4 y = 27
