Ineed with this algebra question, if someone could explain how to solve this i'd appreciate it.

See the attached picture:

Given equation: 3 + x/2 = 10

1st step subtract 3 from each side:

x/2 = 7

2nd step multiply both sides by 2:

x = 14

Step 1)        

3 + x/2 = 10 This is given

Step 2)

x/2 = 7 Multiplication property of equality.

This step is wrong. This step is called "Subtraction property of equality". This means you have to subtract 3 from both sides

3 + x/2 - 3 = 10 - 3

Simplifying

x/ 2 = 7

Step 3)

x = 14 This is called "Multiplication property of equality" because you multiply both sides by 2.

Hope that helps.
