Question

If four times a certain number, increased by 6 is equal to 94, what is the number? If x represents the number, then which of the following equations could be used to solve the problem?

Answer 1

X=22

Explanation:

a certain number will be represented by using x

therefore four times x = 4×x= 4x

Increased by 6 = 4x+6 which is equal to 94

The quation will look like this

4x+6=94

Subtract each side by 6

= 4x+6-6 =94-6

= 4x= 88

Divide each side by 4

4x÷4 =88÷4

= x= 22

Therefor x = 22
