eight times the difference of a number and 3 is 40

Question

help solve equation?

Answer 1

Rewrite the sentence as an equation:

 

8(x-3)=40

 

Distribute: 8x-24=40

Add 24 to both sides: 8x=64

Divide both sides by 8: x=8

 

 

Answer 2

let the number be x

difference of number and 3=x-3

eight times of the above difference = 40

i.e.                                   8*(x-3) =40

 

solve and and find x 

Answer 3

8*(n-3)=40

divide both sides by 8

n-3=5

n=5+3

n=8

Answer 4

• let number be x
• difference is (x-3)
• eight times of the difference is 8*(x-3)
• which in question is given and is equal to 40 means
• 8*(x-3)=40, now open the brackets we get
• 8x-24=40, now add +24 into both sides to cancel -24 and leave only x number on the left hand side, we get, 
• 8x=40+24=64,  now divide both sides by 8 to leave x an unknown number on the left we get
• x=8 an answer.
