Answer:
-15/2 =x
Step-by-step explanation:
12(x+5)=4x
Distribute
12x +60 = 4x
Subtract 12x from each side
12x-12x +60 = 4x-12x
60 = -8x
Divide each side by -8
60/-8 = -8x/-8
15/-2 = x
-15/2 =x
Answer:
300 burgers
Step-by-step explanation:
You can set up an equation like this: 50+0.05x=20+0.15x
Then, subtract 0.05x from both sides: 50=20+0.10x
Subtract 20 from both sides: 30=0.10x
Divide by .10 on both sides: 300=x
X represents how many burgers must be sold for the boys to have earned the same amount of money, and that is 300 burgers.
