x-4y=10,-2x+y=1

Solution

x - 4 y = 10, - 2 x + y = 1

Solution

x = - 2, y = - 3

Solution steps

[x - 4 y = 10 - 2 x + y = 1]

Isolate

x

for

x - 4 y = 10 : x = 10 + 4 y

Substitute

x = 10 + 4 y

[- 2 (10 + 4 y) + y = 1]

Simplify

[- 20 - 7 y = 1]

Isolate

y

for

- 20 - 7 y = 1 : y = - 3

For

x = 10 + 4 y

Substitute

y = - 3

x = 10 + 4 (- 3)

10 + 4 (- 3) = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = - 3

Popular Examples

-2x-7y=25,-2x-5y=19

- 2 x - 7 y = 25, - 2 x - 5 y = 19

2x+y=5,0.3x+2y=7

2 x + y = 5, 0.3 x + 2 y = 7

a = 570, a = 7, c = 8

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

10y+7x=2,9-5y-9x=2

10 y + 7 x = 2, 9 - 5 y - 9 x = 2
