x+7y=-2,3x+y=34

Solution

x + 7 y = - 2, 3 x + y = 34

Solution

x = 12, y = - 2

Solution steps

[x + 7 y = - 2 3 x + y = 34]

Isolate

x

for

x + 7 y = - 2 : x = - 2 - 7 y

Substitute

x = - 2 - 7 y

[3 (- 2 - 7 y) + y = 34]

Simplify

[- 6 - 20 y = 34]

Isolate

y

for

- 6 - 20 y = 34 : y = - 2

For

x = - 2 - 7 y

Substitute

y = - 2

x = - 2 - 7 (- 2)

- 2 - 7 (- 2) = 12

x = 12

The solutions to the system of equations are:

x = 12, y = - 2

Popular Examples

5x+3y=26,10x-y=38

5 x + 3 y = 26, 10 x - y = 38

7y+10x-8=2,y-5x-18=0

7 y + 10 x - 8 = 2, y - 5 x - 18 = 0

2x+y=4,2x-2y=10

2 x + y = 4, 2 x - 2 y = 10

3x+2y=-9,5x-y=-2

3 x + 2 y = - 9, 5 x - y = - 2

((3x))/2-((5y))/3 =-2, x/3+y/2 = 13/6

\frac{( 3 x )}{2} - \frac{( 5 y )}{3} = - 2, \frac{x}{3} + \frac{y}{2} = \frac{13}{6}
