5x+10y=50,x-y=7

Solution

5 x + 10 y = 50, x - y = 7

Solution

x = 8, y = 1

Solution steps

[5 x + 10 y = 50 x - y = 7]

Isolate

x

for

5 x + 10 y = 50 : x = 2 (- y + 5)

Substitute

x = 2 (- y + 5)

[2 (- y + 5) - y = 7]

Simplify

[- 3 y + 10 = 7]

Isolate

y

for

- 3 y + 10 = 7 : y = 1

For

x = 2 (- y + 5)

Substitute

y = 1

x = 2 (- 1 + 5)

Simplify

x = 8

The solutions to the system of equations are:

x = 8, y = 1

Popular Examples

-4x-y=19,-x-y=7

- 4 x - y = 19, - x - y = 7

3 x - y = 7, x + 4 y = 11

2x-3y=12,2x+2y=42

2 x - 3 y = 12, 2 x + 2 y = 42

23x+7y=10,2x-9y=0

23 x + 7 y = 10, 2 x - 9 y = 0

y=-x+2,7x+4y=-1

y = - x + 2, 7 x + 4 y = - 1
