Question

Solve using linear combination.

Answer 1

Answer:

(3,5)

Step-by-step explanation

3=e and 5=f (but I guess u accidentally put a plus sign)

so 2e= 6 and 3f=15, and 6-15=-9 so this checks out

Next e=3 and 3f=15 (that 5 in the second problem should be an f)               and 3+15-18 again is checks out so 3,5 must be correct yada yada yada goodnight.

-I'm usually more professional explaining problems but i broke it down for ya, when I get over this drowsiness I'll be back to my usually math pro self

Answer 2

e = -17. 2 x -17 - 3 + 9

-34 - 3 + 9

== -28

hope this helps
