which 3 is multiplied by 5 less than a number,then result is 9 less than 5 times the number.find the number​

Sagot :

Answer:

N = - 22

Step-by-step explanation:

Step 1: Write the algebraic expression.

3(x-5) = 5x-93(x−5)=5x−9

wherein:

xx is the number

Understanding algebraic expression

"5 less than a number" is written as "x-5x−5 "

"result" means "is equal to"

"9 less than 5 times the number" is written as "5x-95x−9 "

"7 less than 5 times the number" is written as "5x-75x−7 "

Step 2: Solve for the value of xx using distributive property of multiplication

3(x-5) = 5x-93(x−5)=5x−9

3x-15 = 5x-93x−15=5x−9

-2x = 6−2x=6

x = -3x=−3

Step 3: Find the "7 less than 5 times the number" by substituting the value of xx

N=5x-7N=5x−7

where NN is the desired output

N=5(-3)-7N=5(−3)−7

N=-15-7N=−15−7

N=-22N=−22
