Explain why the rules called the algebraic order of operations are necessary for computation

1 answer:

5 0

The rules are necessary, so that there is agreement as to how to evaluate an expression. By having rules, and having everyone follow the rules, an expression can have only one single correct value. If there are no rules, then different people will interpret the expression differently, and will get different values for its evaluation.

Step-by-step explanation:

if x+y=24

x= 24- y

in second case

x= 3y

Solve for x y=c(x+b)

sergeinik [125]

Step-by-step explanation: To solve for x in this literal equation, I would first distribute the C through the parentheses to get y = cx + cb.

Now subtract cb from both sides to get y - cb = cx.

Finally, divide both sides by c to get y - cb / c = x.
