Answer:
No, 8+10=18 but, 14+10=24 which means x=14
Step-by-step explanation:
Archy: 15 gallons ... $23.85
1 gallon ...$ x = ?
x * 15 = 1 * 23.85 /15
x = 23.85 / 15
x = $1.59 per gallon
Joe: 16 gallons ... $24.48
1 gallon ... $ y = ?
y * 16 = 1 * 24.48 /16
y = 24.48 / 16
y = $1.53 per gallon
Result: Joe paid less per gallon.
Ok let's do this*pops knuckles*
let's add the first side

order of operations demands that we do multiplication first(P.E.M.D.A.S)
so

now we can add the 1 from

into our six

now we substract

now we have

now we focus on the
other side

since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.

now we have

(the three is from the original equation)
now we plug in our final numbers

or
