Question

5 less than 4 times a number is the same as 9 times the number.

Answer 1

Hi, there.

 _____

"5 less than 4 times a number" 4x-5

"is the same as" =

"9 times the number" 9x

Putting the parts together,

$\boldsymbol{4x-5=9x}$

Solving the two step equation

$\boldsymbol{4x-9x=5}$

$\boldsymbol{-5x=5}$

Divide both sides by -5

$\boldsymbol{x=-1}$

So the A answer checks.

Hope the answer - and explanation - made sense,

happy studying!!
