Answer 1

Answer:

a)

We suppose that the number is x. So,

5 times a number = 5x

The equation for the given statement is,

5x = 45

x = 45/5

x = 9

5 times a number 9 is equal to 45.

b)

The sum of the number x and twice the number y is = x + 2y

So, the equation is,

x +2y = 12

c)

We assume that the number is x. So,

4 times a number = 4x

So, 3 less than 4 times a number is 17. The equation will be,

4x - 3 = 17

4x = 17 + 3

4x = 20

x = 20/4

x = 5

So, the number is 5.
