x-2y=17,7x-6y=47

Solution

x - 2 y = 17, 7 x - 6 y = 47

Solution

x = - 1, y = - 9

Solution steps

[x - 2 y = 17 7 x - 6 y = 47]

Isolate

x

for

x - 2 y = 17 : x = 17 + 2 y

Substitute

x = 17 + 2 y

[7 (17 + 2 y) - 6 y = 47]

Simplify

[119 + 8 y = 47]

Isolate

y

for

119 + 8 y = 47 : y = - 9

For

x = 17 + 2 y

Substitute

y = - 9

x = 17 + 2 (- 9)

17 + 2 (- 9) = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = - 9

Popular Examples

2x+7y=17,5x+3y=-1

2 x + 7 y = 17, 5 x + 3 y = - 1

x + y = 2, x - y = 20

5x+3y=-7,3x-2y=-8

5 x + 3 y = - 7, 3 x - 2 y = - 8

4x-2y=16,3x-4y=7

4 x - 2 y = 16, 3 x - 4 y = 7

4x+10y=-4,6x-15y=0

4 x + 10 y = - 4, 6 x - 15 y = 0
