Question

How many solutions are there for the following equation? Why?

8(x+9)=72−5x

Answer 1

1 solution , x = 0

Explanation:

8(x + 9) = 72 - 5x ← distribute parenthesis on left side

8x + 72 = 72 - 5x ( add 5x to both sides )

13x + 72 = 72 ( subtract 72 from both sides )

13x = 0 ⇒ x = 0

x = 0 is the only solution to the equation
