solve the system of linear equations using the gauss-jordan elimination method.

2x + 10y = 21

−6x + 8y = 32

x = -2

y = 5/2

Step-by-step explanation:

See it in the pic.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
