x equals 4 and y equals 5 . so the formula would be 5x+12y=80 and if we need 4 of the small boxes we sub x for 4 and we get 5(4) =20. Next, 80 minus 20 is 60, and the equation would now be 12y=60. we now divide both sides by 12 and we get left with y=5. 5x + 12y = 80 5(4) + 12(5)=80 20+60=80. That is all. I hope that doesn't sound confusing
Answer:
11/5
Step-by-step explanation:
2x+12+4-12x+6
-10x+22
x=22/10
x= 11/5
22/5+12+4=123/5-6
102/5=123/5-30/5
102/5=97/5
102/5-97/5
5/5
