Question

An equation is shown below: 5(2x - 8) + 15 = -15 Write the steps you will use to solve the equation and explain each step. (5 points)

Answer 1

x = 1

Explanation:

5(2x - 8) + 15 = -15

Subtract 15 both sides

5(2x - 8) = -30

Divide both sides by 5

2x - 8 = -6

Add 8 both sides

2x = 2

Divide both sides by 2

x = 1

Answer 2

x=1

Explanation:

To solve this question we will have to open the bracket first

So let's solve the question

5(2x-8)+15=-15

Bracket first

10x-40+15=-15

We will have to solve the question further

10x-25=-15

Add 25 to both sides

10x=10

Let's make x the subject of formula by dividing both sides by 10

x=1

Therefore x is 1
