Question

9+4(x+1)=25

Answer 1

first use PEMDAS aka order of operations
distribute the 4(x+1)
now you have
9+4x+4=25
then add like terms on the left side (9+4)
now you have:
13+4x=25
then move the 13 to the other side by subtracting it from the left side
now you have
4x=25
then divide by 4
and your answer is?
(25/4)

Answer 2

formally you would write x=(25/4)

Answer 3

x=6.25 ???

Answer 4

first use PEMDAS aka order of operations
distribute the 4(x+1)
now you have
9+4x+4=25
then add like terms on the left side (9+4)
now you have:
13+4x=25
then move the 13 to the other side by subtracting it from the left side
now you have
4x=12
then divide by 4
and your answer is?
3
x=3
(My first answer was wrong because I forgot to subtract the 13 on both sides)
*if you ever are unsure about an answer to a problem simply plug in the answer for x and see if both sides equal the same number
