x+y=17,5x-4y=-5

Solution

x + y = 17, 5 x - 4 y = - 5

Solution

x = 7, y = 10

Solution steps

[x + y = 17 5 x - 4 y = - 5]

Isolate

x

for

x + y = 17 : x = 17 - y

Substitute

x = 17 - y

[5 (17 - y) - 4 y = - 5]

Simplify

[85 - 9 y = - 5]

Isolate

y

for

85 - 9 y = - 5 : y = 10

For

x = 17 - y

Substitute

y = 10

x = 17 - 10

Simplify

x = 7

The solutions to the system of equations are:

x = 7, y = 10

Popular Examples

8x-6y=12,6x+4y=26

8 x - 6 y = 12, 6 x + 4 y = 26

2 x - y = 1, 2 y = x

2x+7y=17,5x+4y=2

2 x + 7 y = 17, 5 x + 4 y = 2

x+4y-z=12,3x+8y-2z=4

x + 4 y - z = 12, 3 x + 8 y - 2 z = 4

(2)x-3y=1,3x-2y+4=0

(2) x - 3 y = 1, 3 x - 2 y + 4 = 0
