Question

16 added 3 times a number is equal to 4 added to 5times the number. what is the number​

Answer 1

Answer:

3

Explanation:

(5r+3)4=72

Let r=the number

The “sum” of 5 times a number plus 3 multiplied by 4 to make 72 can be denoted by the mathematical statement:

(5r+3)4=72

[(5r+3)4]/4=72/4 [Divide both sides of the equation by 4]

5r+3=18

5r/5+(3–3)=(18–3)/5

r+0=15/5

r=3
