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

Solution

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

Solution

x = 3, y = 2

Solution steps

[x - y = 1 x - 3 y = - 3]

Isolate

x

for

x - y = 1 : x = 1 + y

Substitute

x = 1 + y

[1 + y - 3 y = - 3]

Simplify

[1 - 2 y = - 3]

Isolate

y

for

1 - 2 y = - 3 : y = 2

For

x = 1 + y

Substitute

y = 2

x = 1 + 2

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = 2

Popular Examples
