Question

What is the value of X?

Answer 1

Hi there! The answer is x = 6

Since the length of both sides is the same, we get the following equation:
$5x + 10 = 40$

Subtract 10 from both sides
$5x = 30$

Divide both sides by 5.
$x = 30 \div 5 = 6$

Answer 2

The two sides are congruent (because of the straight line through the side)

set them equal to one another

5x + 10 = 40

Isolate the x, do the opposite of PEMDAS

5x + 10 = 40

subtract 10 from both sides

5x + 10 (-10) = 40 (-10)

5x = 30

divide 5 from both sides

5x/5 = 30/5

x = 30/5

x = 6

6 is your answer for x

hope this helps
