-x-2y=10,4x+4y=4

Solution

- x - 2 y = 10, 4 x + 4 y = 4

Solution

x = 12, y = - 11

Solution steps

[- x - 2 y = 10 4 x + 4 y = 4]

Isolate

x

for

- x - 2 y = 10 : x = - 10 - 2 y

Substitute

x = - 10 - 2 y

[4 (- 10 - 2 y) + 4 y = 4]

Simplify

[- 40 - 4 y = 4]

Isolate

y

for

- 40 - 4 y = 4 : y = - 11

For

x = - 10 - 2 y

Substitute

y = - 11

x = - 10 - 2 (- 11)

- 10 - 2 (- 11) = 12

x = 12

The solutions to the system of equations are:

x = 12, y = - 11

Popular Examples

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

a = 2, b = 3, c = 4

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

a+b+c=0,a-3b+c=1,-2a-1c=-1

a + b + c = 0, a - 3 b + c = 1, - 2 a - 1 c = - 1

2x-5y=14,3x+y=4

2 x - 5 y = 14, 3 x + y = 4
