1/7+2x/3=(15x-3)/21 make all terms have a common denominator of 21
3+14x=15x-3 subtract 3 from both sides
14x=15x-6 subtract 15x from both sides
-x=-6 divide both sides by -1
x=6
*Notice the use of parentheses in this format to make it clear what the numerators and denominators are...
Answer:
x = no.of months
y = cost
f(12) = 30x+75
f(12) = 30(12)+75
f(12) = 360+75
f(12) = 435
Therefore it cost him $435 in 12 months.

Answer:
Addition and Subtracttion
Step-by-step explanation:
The order of operations has to with a generally accepted order to follow when evaluating a mathematical expression.
PEDMAS or BODMAS is the order of operations to follow.
The two operations that are on the same level within the order of operations are addition and subtracttion
This means that, neither has a preference over the other.
