Question

Translate each of the following statements into an equation, using x as the
variable:
(a) 13 subtracted from twice a number gives 3.
(b) One fifth of a number is 5 less than that number.

Answer 1

Answer:

(a)2x-13=3

(b) 1/5=x-5

Answer 2

a) Let the number be = x

twice the number = 2x

13 subtracted from it = 2x - 13

it gives 3

2x - 13 = 3

Equation is 2x - 13 = 3

b) Let the number be = x

1/5 of the number = 1/5 of x = x/5

it is equal to 5 less than the number = x - 5

x/5 = x - 5

Equation is x/5 = x - 5
