Question

What is the value of x in the equation 5(3x + 4) = 23?

Answer 1

`x = 0.2`

Explanation:

Step 1: Distribute

`5(3x + 4) = 23`

`(5 * 3x) + (5 * 4) = 23`

`(15x) + 20 = 23`

Step 2: Subtract 20 from both sides

`(15x) + 20 - 20 = 23 - 20`

`15x = 3`

Step 3: Divide both sides by 15

`(15x)/(15) = (3)/(15)`

`x = (1)/(5)`

`x = 0.2`

Answer:
`x = 0.2`

Answer 2

x = 1/5

Explanation:

5(3x + 4) = 23

Distribute

15x+20 = 23

Subtract 20 from each side

15x+20-20 = 23-20

15x = 3

Divide by 15

15x/15 = 3/15

x = 1/5
