Slimination
the teacher probably wants you to eliminate the x terms since there are an equal number of them
so multiply first equation by -1
-6x+3y=-30
add to second equation
6x-6x+3y+y=18-30
0x+4y=-12
4y=-12
divide by 4
y=-3
subsitute
6x+-3=18
add 3
6x=21
divide both sides by 6
x=21/6=7/2
x=7/2
y=-3
Answer:
369/10
Step-by-step explanation:

3 3/5=18/5
----------------
(41/4)(18/5)=738/20
simplify
369/10
