Question

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

Answer 1

Answer:

$x = \frac { 1 } { 5 }$

Step-by-step explanation:

We are given the following equation and we are to find the value of x by making it the subject of the equation:

$5 ( 3 x + 4 ) = 23$

We will start by opening the brackets and expanding the term by multiplying 5 with the terms inside the brackets to get:

$15 x + 20 = 23$

$15 x = 23 - 20$

$15 x = 3$

$x = \frac { 3 } { 15 }$

$x = \frac { 1 } { 5 }$

Answer 2

Fraction form: 1/5

Decimal form: 0.2



First, distribute the 5 to the (3x + 4).

15x + 20 = 23

Subtract 20 from both sides.

15x = 3

Now divide by 15 on both sides.

x = 1/5

Keep in mind 1/5 is also 0.2 in decimal form.

There’s the answer.
