Question

How many solutions are there to the equation below?

12x + 6 = 5x

A. 0

B. Infinitely many

C. 1

Answer 1

C

Explanation:

This is a linear equation in one variable and has 1 solution

12x + 6 = 5x ( subtract 5x from both sides )

7x + 6 = 0 ( subtract 6 from both sides )

7x = - 6 ( divide both sides by 7 )

x = -
`(6)/(7)` ← 1 solution
