Solve by Graphing x-y=2 , x+y=6

x - y = 2, x + y = 6

x = 4, y = 2

Solution steps

[x - y = 2 x + y = 6]

Isolate

x

for

x - y = 2 : x = 2 + y

Substitute

x = 2 + y

[2 + y + y = 6]

Simplify

[2 + 2 y = 6]

Isolate

y

for

2 + 2 y = 6 : y = 2

For

x = 2 + y

Substitute

y = 2

x = 2 + 2

Simplify

x = 4

The solutions to the system of equations are:

x = 4, y = 2

3 c - 2 (c + 10)

\frac{1}{( cos ( x ) )}

u, 8 u - 8 u + u = 4

\frac{32}{18}
