Question

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

Answer 1

Answer:

x = 1/5

Step-by-step 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

Answer 2

Answer:

$x = 0.2$

Step-by-step 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

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

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

$x = 0.2$

Answer:  $x = 0.2$
