Answer 1

The properties that were used to solve the problem are:

• step 1: addition property of equality
• step 2: additive inverses
• step 3: additive identity
• step 4: multiplication property of equality

How to solve the problem

Given: c/2-5=7

we are to solve for C

ste[p 1 addition property of equality

• c/2-5+5=7+5

Step 2: additive inverses

• c/2+0=12

step 3: additive identity

• c/2=12

step 4: multiplication property of equality

2 (c/2)=12(2)

Step 5: c=24

The value of C is given as 24

Study the steps used to solve the equation. Given: c/2-5=7 Step 1: c/2-5+5=7+5 Step 2: c/2+0=12 Step 3: c/2=12 Step 4: 2 (c/2)=12(2) Step 5: c=24 Choose the property that justifies each step of the solution.

Answer 2

c = 24

Explanation:

The given equation is :

`(c)/(2)-5=7`

Adding both sides by 5 both sides,

`(c)/(2)-5+5=7+5\\\\(c)/(2)=12`

Cross multiplying both sides,

`c=2* 12`

c = 24

So, the value of c is 24.
