x+y=4,x-y=6

Solution

x + y = 4, x - y = 6

Solution

x = 5, y = - 1

Solution steps

[x + y = 4 x - y = 6]

Isolate

x

for

x + y = 4 : x = 4 - y

Substitute

x = 4 - y

[4 - y - y = 6]

Simplify

[4 - 2 y = 6]

Isolate

y

for

4 - 2 y = 6 : 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
