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

Solution

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

Solution

x = - 3, y = 4

Solution steps

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

Isolate

x

for

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

Substitute

x = 5 - 2 y

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

Simplify

[10 - 3 y = - 2]

Isolate

y

for

10 - 3 y = - 2 : y = 4

For

x = 5 - 2 y

Substitute

y = 4

x = 5 - 2 \cdot 4

Simplify

x = - 3

The solutions to the system of equations are:

x = - 3, y = 4

Popular Examples

3x+4y=14,5x+2y=14

3 x + 4 y = 14, 5 x + 2 y = 14

g(x)=10x,g(x)=15

g (x) = 10 x, g (x) = 15

(2a-1)*x+3y=5,3x+(b-1)*y=15

(2 a - 1) \cdot x + 3 y = 5, 3 x + (b - 1) \cdot y = 15

x + y = 4, 2 x = 5 y

5x-2y=16,2x-3y=13

5 x - 2 y = 16, 2 x - 3 y = 13
