x+2y=7,x-2y=-1

Solution

x + 2 y = 7, x - 2 y = - 1

Solution

x = 3, y = 2

Solution steps

[x + 2 y = 7 x - 2 y = - 1]

Isolate

x

for

x + 2 y = 7 : x = 7 - 2 y

Substitute

x = 7 - 2 y

[7 - 2 y - 2 y = - 1]

Simplify

[7 - 4 y = - 1]

Isolate

y

for

7 - 4 y = - 1 : y = 2

For

x = 7 - 2 y

Substitute

y = 2

x = 7 - 2 \cdot 2

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = 2
