x+3y=1,-x+2y=4

Solution

x + 3 y = 1, - x + 2 y = 4

Solution

x = - 2, y = 1

Solution steps

[x + 3 y = 1 - x + 2 y = 4]

Isolate

x

for

x + 3 y = 1 : x = 1 - 3 y

Substitute

x = 1 - 3 y

[- (1 - 3 y) + 2 y = 4]

Simplify

[- 1 + 5 y = 4]

Isolate

y

for

- 1 + 5 y = 4 : y = 1

For

x = 1 - 3 y

Substitute

y = 1

x = 1 - 3 \cdot 1

Simplify

x = - 2

The solutions to the system of equations are:

x = - 2, y = 1

8x+6y=10,-3x+6y=-12

8 x + 6 y = 10, - 3 x + 6 y = - 12

4x-7y=3,-2x-2y=-18

4 x - 7 y = 3, - 2 x - 2 y = - 18

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

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

-5x+y=6,5x-7y=18

- 5 x + y = 6, 5 x - 7 y = 18

72x+3y=6,3x-2y=7

72 x + 3 y = 6, 3 x - 2 y = 7
