Let's see how to solve this.....substitute in each value as x, do the operations and find out which one is true! I'll help you out!

kamibug · Answer

Add 1 to both sides then divide both sides by 2.

igreen · Answer

2x - 1 = 9

Add 1 to both sides.

2x = 9 + 1

2x = 10

Now, can you divide 10 / 2?

emmamink · Answer

Let's start with adding one and then dividing each side by two. This is called the addition property of equality and the multiplication property of equality. We now have x = 5!
