x-y=3,2x+y=12

Solution

x - y = 3, 2 x + y = 12

Solution

x = 5, y = 2

Solution steps

[x - y = 3 2 x + y = 12]

Isolate

x

for

x - y = 3 : x = 3 + y

Substitute

x = 3 + y

[2 (3 + y) + y = 12]

Simplify

[6 + 3 y = 12]

Isolate

y

for

6 + 3 y = 12 : y = 2

For

x = 3 + y

Substitute

y = 2

x = 3 + 2

Simplify

x = 5

The solutions to the system of equations are:

x = 5, y = 2

4 x + 6 y = 24, 2 x + 3 y = 6

x + 3 y = - 1, 2 x - y = 5

x-3y+2z=-3,5x+6y-z=13,4x-y+3z=8

x - 3 y + 2 z = - 3, 5 x + 6 y - z = 13, 4 x - y + 3 z = 8

5x-3y-z=1,x+4y-6z=-1,2x+3y+4z=9

5 x - 3 y - z = 1, x + 4 y - 6 z = - 1, 2 x + 3 y + 4 z = 9

x+3y=6,5x-2y=13

x + 3 y = 6, 5 x - 2 y = 13
