Question

Solve the following system of equations:

 

x+5y=-29

-5x-2y=30

answer (x,y)

Answer 1

Substitute the first equation into the second equation.  From the first equation,

 

x = -5y - 29

 

 

Substituting this value of x into the second equation,

 

-5(-5y - 29) - 2y = 30

 

 

Solve for y from this equation.  Take it from here.

Answer 2

Help YOURSELF, as follows.

Solve for x, using the first equation.

Substitute that x value in the second equation & solve for y.

 

Congratulations.  Check that your ordered pair (x,y) really does 'satisfy' both equations.
