Question

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

a. x = -1
b. x = 1
c. x = -2

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!!
