x+2y=8,-x+3y=17

Solution

x + 2 y = 8, - x + 3 y = 17

Solution

x = - 2, y = 5

Solution steps

[x + 2 y = 8 - x + 3 y = 17]

Isolate

x

for

x + 2 y = 8 : x = 8 - 2 y

Substitute

x = 8 - 2 y

[- (8 - 2 y) + 3 y = 17]

Simplify

[- 8 + 5 y = 17]

Isolate

y

for

- 8 + 5 y = 17 : y = 5

For

x = 8 - 2 y

Substitute

y = 5

x = 8 - 2 \cdot 5

Simplify

x = - 2

The solutions to the system of equations are:

x = - 2, y = 5
