Can someone me solve these systems using elimination? i have a hard time with these.
8x-6y=-20
-16x+17y=30
and then..
-4y-11x=36
20= -10x-10y
show the steps so i can learn too. you!

Question 1:

For this case we must solve the following system of equations by the method of elimination:

We multiply the first equation by 2:

We have the equivalent system:

We add the equations:

We divide between 5 on both sides of the equation:

We find the value of the variable "x":

We divide by 8 on both sides of the equation:

Thus, the solution of the system is:

Question 2:

For this case we must solve the following system of equations by the method of elimination:

We multiply the first equation by 10:

We multiply the second equation by -4:

We have the equivalent system:

We add the equations:

We divide by -70 on both sides of the equation:

We find the value of the variable "y":

We divide between -4 on both sides of the equation:

Thus, the solution of the system is:
