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

Solution

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

Solution

x = - 6, y = 4

Solution steps

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

Isolate

x

for

x + 2 y = 2 : x = 2 - 2 y

Substitute

x = 2 - 2 y

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

Simplify

[- 2 + 3 y = 10]

Isolate

y

for

- 2 + 3 y = 10 : y = 4

For

x = 2 - 2 y

Substitute

y = 4

x = 2 - 2 \cdot 4

Simplify

x = - 6

The solutions to the system of equations are:

x = - 6, y = 4

Popular Examples

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

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

x/(10)+y/5 =1,4 x/8+y/6 =15

\frac{x}{10} + \frac{y}{5} = 1, 4 \frac{x}{8} + \frac{y}{6} = 15

x + y = 2, 5 x - y = 5

2x-5y=20,-3(x-y)+y=-2

2 x - 5 y = 20, - 3 (x - y) + y = - 2

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