Answer:
The answer is
3P+2B=15.50
P+4B=20
Where P=pizza slice and B=burger
B=4.45
P=2.20
Step-by-step explanation:
The system proposal is
3P+2B=15.50
P+4B=20
Solving for P in the second equation, we have
P=20-4B and replace in first equation we have:
3(20-4B)+2B=15.50
Solving for B:
B=(60-15.5)/10=4.45
Replace B in first equation
P=20-4B=20-4(4.45)=2.20
Answer:
x = 33/5
Step-by-step explanation:
x - 3/5 = n.......n = 6
so we sub
x - 3/5 = 6......add 3/5 to both sides
x = 6 + 3/5...convert using common denominator of 5
x = 30/5 + 3/5
x = 33/5 <===
check...
x - 3/5 = 6
33/5 - 3/5 = 6
30/5 = 6
6 = 6 (correct)...so it checks out
