Question

What is the value of x in the equation 3(2x + 5) = 16?

1/6
31/6
6/31
7/3

Answer 1

x =
`(1)/(6)`

Explanation:

Given

3(2x + 5) = 16 ← distribute left side

6x + 15 = 16 ( subtract 15 from both sides )

6x = 1 ( divide both sides by 6 )

x =
`(1)/(6)`

Answer 2

3(2x+5)=16
6x+15=16

Subtract 15 on each side

6x=1

Divide by 6 on each side

x=1/6
