Answer:

R = 4

s = -3

Step-by-step explanation:

r + 4s = -8

3r + 2s = 6

there are several ways to solve this system but i chose the elimination method and multiplied the second equation by -2 to get:

  -6r - 4s = -12 and added it to the first equation

+ <u> 1r + 4s =  -8</u>

 -5r = -20

   r = 4

plug in to find 's':  4 + 4s = -8

                              4s = -12

                               s = -3

7x + 4y = -3<br> -7x - 5y = 9<br> How do I solve using elimination
mel-nik [20]

Answer:

X=3, y=-6

Step-by-step explanation:

7x+4y=-3 equation 1

-7x-5y=9 equation 2

     -y=6. Add above two equations    

      Y=-6

solve for x by inputting y value into either equation.

7x+4(-6)=-3

7x-24=-3

7x=21

x=3

check answer by inputting x and y values into either equation

-7x-5y=9

-7(3)-5(-6)=9

–21+30=9

9=9
