x+y=14,x-y=4

Solution

x + y = 14, x - y = 4

Solution

x = 9, y = 5

Solution steps

[x + y = 14 x - y = 4]

Isolate

x

for

x + y = 14 : x = 14 - y

Substitute

x = 14 - y

[14 - y - y = 4]

Simplify

[14 - 2 y = 4]

Isolate

y

for

14 - 2 y = 4 : y = 5

For

x = 14 - y

Substitute

y = 5

x = 14 - 5

Simplify

x = 9

The solutions to the system of equations are:

x = 9, y = 5
