x+2y=5,2x-y=-5

Solution

x + 2 y = 5, 2 x - y = - 5

Solution

x = - 1, y = 3

Solution steps

[x + 2 y = 5 2 x - y = - 5]

Isolate

x

for

x + 2 y = 5 : x = 5 - 2 y

Substitute

x = 5 - 2 y

[2 (5 - 2 y) - y = - 5]

Simplify

[10 - 5 y = - 5]

Isolate

y

for

10 - 5 y = - 5 : y = 3

For

x = 5 - 2 y

Substitute

y = 3

x = 5 - 2 \cdot 3

Simplify

x = - 1

The solutions to the system of equations are:

x = - 1, y = 3

2 x + \frac{3}{2} y = 1, 4 x + \frac{1}{3} y = 3

5 x + y = 4, x - 2 y = 3

2 a = 5, - 3 b = 2

x + y = 2, x - y = 0

x + y = 3, x - y = 1
