x+3y=5,2x-3y=-8

Solution

x + 3 y = 5, 2 x - 3 y = - 8

Solution

x = - 1, y = 2

Solution steps

[x + 3 y = 5 2 x - 3 y = - 8]

Isolate

x

for

x + 3 y = 5 : x = 5 - 3 y

Substitute

x = 5 - 3 y

[2 (5 - 3 y) - 3 y = - 8]

Simplify

[10 - 9 y = - 8]

Isolate

y

for

10 - 9 y = - 8 : y = 2

For

x = 5 - 3 y

Substitute

y = 2

x = 5 - 3 \cdot 2

Simplify

x = - 1

The solutions to the system of equations are:

x = - 1, y = 2

7 x - 4 y = 5, 9 x + 8 y = 13

3x+2y=-12,2x-3y=5

3 x + 2 y = - 12, 2 x - 3 y = 5

3x+y=1,-4x-3y=7

3 x + y = 1, - 4 x - 3 y = 7

8x+3y=30,5x+3y=21

8 x + 3 y = 30, 5 x + 3 y = 21

8x+7y=10,11x=10-10y

8 x + 7 y = 10, 11 x = 10 - 10 y
