Question

The product of six and the sum of a number and two had the same value as two less than the product of the same number and twenty

Answer 1

The value of the unknown number is equal to 1.

6(x + 2) = 20x - 2

Distributive property.

6x + 12 = 20x - 2

Subtract 6x from both sides.

12 = 14x - 2

Add 2 to both sides.

14 = 14x

Divide both sides by 14.

x = 1
