A certain number is added to 11 and the result is multiplied by 3, the final result is 45. Find the number
Answered by oobleck
(x+11)*3 = 45
solve for x
Answered by Benjamin
(11+x)(3)=45
Answered by Benjamin
(11+x)(3)=45
33+3x=45
3x=45-33
3x=12
By dividing both sides by 3
3x/3=12/3
X=4

Let's put it and see the answer.
(11+4)(3)=45
33+12=45
45=45
Therefore, the number (x) is equal to 4 (x=4)
Answered by Sandra
Let x be the number
(11+x)(3)=45
33+3x=45
3x=45-33
3x=12
You will divide both sides by 3
3 will cancel 3 and goes into 12 =4
Therefore x=4
