x-5y=31,3x+5y=-7

Solution

x - 5 y = 31, 3 x + 5 y = - 7

Solution

x = 6, y = - 5

Solution steps

[x - 5 y = 31 3 x + 5 y = - 7]

Isolate

x

for

x - 5 y = 31 : x = 31 + 5 y

Substitute

x = 31 + 5 y

[3 (31 + 5 y) + 5 y = - 7]

Simplify

[93 + 20 y = - 7]

Isolate

y

for

93 + 20 y = - 7 : y = - 5

For

x = 31 + 5 y

Substitute

y = - 5

x = 31 + 5 (- 5)

31 + 5 (- 5) = 6

x = 6

The solutions to the system of equations are:

x = 6, y = - 5

Popular Examples

x - y = 1, x - 3 y = - 3

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

12x-7y=15,3x+6y=4

12 x - 7 y = 15, 3 x + 6 y = 4

2 x - y = 6, 2 x + y = 10

1 b = - 3, 2 c = 256
