Question

three added to 7 times of a number gives 38 . a) how much is 4 times that number?
, b) if 5 is subtracted from 3 times of a number , what is the number ?

Answer 1

Answer:

a)20, b)10

Step-by-step explanation:

let the number be: x

3+7x= 38

7x= 38-3

7x=35

x=35/7

x=5

a) 4 times x= 4×x

=4×5

=20

b) 5 subtracted from 3 times x=(3×x)-5

=(3×5)-5

=15-5

=10
