y=2x+7,-6x-2y=-4

Solution

y = 2 x + 7, - 6 x - 2 y = - 4

Solution

x = - 1, y = 5

Solution steps

[y = 2 x + 7 - 6 x - 2 y = - 4]

Substitute

y = 2 x + 7

[- 6 x - 2 (2 x + 7) = - 4]

Simplify

[- 10 x - 14 = - 4]

Isolate

x

for

- 10 x - 14 = - 4 : x = - 1

For

y = 2 x + 7

Substitute

x = - 1

y = 2 (- 1) + 7

2 (- 1) + 7 = 5

y = 5

The solutions to the system of equations are:

x = - 1, y = 5

Popular Examples

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

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

x-3y=3,x-1=2x-y

x - 3 y = 3, x - 1 = 2 x - y

2 x - 3 y = 11, 3 x = - y

-6x-2y=-48,5x+2y=60

- 6 x - 2 y = - 48, 5 x + 2 y = 60

x-11-2x-3y=-7,y=6

x - 11 - 2 x - 3 y = - 7, y = 6
