x-y=4,2x-y=9

Solution

x - y = 4, 2 x - y = 9

Solution

x = 5, y = 1

Solution steps

[x - y = 4 2 x - y = 9]

Isolate

x

for

x - y = 4 : x = 4 + y

Substitute

x = 4 + y

[2 (4 + y) - y = 9]

Simplify

[8 + y = 9]

Isolate

y

for

8 + y = 9 : y = 1

For

x = 4 + y

Substitute

y = 1

x = 4 + 1

Simplify

x = 5

The solutions to the system of equations are:

x = 5, y = 1
