Answer 10

Lets start with the first one. We have two objects, one weighs 3 and the other weighs w. We need the sum of their weights to be 7. In mathematical notation \(3+w=7\). By subtracting \(3\) from both sides, we get \(w=7-3=4\).

Answer 11

omg! blunder!

Answer 12

For the second problem, there are 5 objects each weighs n and they add up to 25 mass unit. That's \(5n=25 \implies n=\frac{25}{5}\iff n=5\).

Answer 13

Tell me how much does x weigh in problem 3.

Answer 14

3? but i need help with showing work??

Answer 15

Correct! You have \[x+x+7=`3\]

Answer 16

x plus x is 2x. So
\[2x+7=13\]

Answer 17

Now, you need to isolate x from any number. So subtract 7 from both sides,
\(2x+7-7=13-7\), which is the same as
\[2x=6\]

Answer 18

Now, you want to get rid of x's coefficient. Divide both sides by 2:
\[x=3.\]
