The problem can be solved by substituting your numerical values for the variables in the equation.
You have been told that...
- Substitute the v in the equation for 10
- Substitute the in the equation for 5
Now, rewrite your expression with the numbers now in the place of the variables:
+ 3
Now solve!
2 × 10 = 20
20 ÷ 5 = 4
4 + 3 =7
Your answer is 7!
