system of equations

[Raven]

solve the system of equations. If the system of equations is dependent then set one of the variables equal to the real number c, and express the other variables in terms of c.



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

state whether independent dependent or in consistent
show answers to independent or dependent system of equations




assuming you need to do substitution?

 

[Loren]

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

One approach to get started is to substitute the value given for x in the second equation into the first equation and solve for y. I'll get you started.

2(-3y-1) + 5y = -3

Now, go ahead and solve for y. When you have the value of y, plug that value back into either equation and solve for x.
