Question

One half of a number added to itself is equal to 6

Answer 1

x = a number

x + x / 2 = 6

2 x / 2 + x / 2 = 6

3 x / 2 = 6 Multiply both sides by 2

3 x = 12 Divide both sides by 3

x = 12 / 3 = 4

Proof ;

4 / 2 + 4 = 2 + 4 = 6

Answer 2

X=6

Answer 3

This was very helpful to my daughter as she was struggling with this question so thank u very much for this as now we know the method and how to work problems like this out we are very thankful for the people who took their time in helping us by answering the question and we will continue looking forward to your help when we need it thank you once again

Answer 4

x/2+x/2=6
x/2. =6
x*2. =6*2
x=12

Answer 5

Correct! Another way of solving the equation is by combining the two x/2 terms to get:

x/2 + x/2 = 2x/2 = x

So the equation becomes:

x = 6

Multiplying both sides by 2:

2x = 12

Dividing both sides by 2:

x = 6

So x is indeed equal to 12. Well done!
