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

Solution

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

Solution

x = 2, y = 3

Solution steps

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

Isolate

x

for

- x + y = 1 : x = - 1 + y

Substitute

x = - 1 + y

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

Simplify

[- 2 + y = 1]

Isolate

y

for

- 2 + y = 1 : y = 3

For

x = - 1 + y

Substitute

y = 3

x = - 1 + 3

Simplify

x = 2

The solutions to the system of equations are:

x = 2, y = 3

Popular Examples

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

4x+2y=3,-4x+y=6

4 x + 2 y = 3, - 4 x + y = 6

52x+65y=18,365x+52y=168

52 x + 65 y = 18, 365 x + 52 y = 168

f(x)=3,x+1x^0=2

f (x) = 3, x + 1 x^{0} = 2

3y=6x+3,-9x-9=-5y

3 y = 6 x + 3, - 9 x - 9 = - 5 y
