REal number can someone explain what it is in their own words please

Real numbers are numbers that are all on the number line. They can be negative and positive. Also, the number 0 can be a real number.

Hope this helps

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
