Question

The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul’s age. Nixon’s first presidential election happened 39 years after the Great Depression. Using the given information, write an equation to find Raul’s age, r.

Answer 1

Raul is 15 years old.

Explanation:

The number of years from the start of the Great Depression to Nixon's election is six years less than three times Raul's age: 3r-6

If then Nixon's first election happened 39 years after the Great Depression, then: 3r-6=39

3r-6=39 Add six to both sides so the 6 on the left side gets canceled out (positive and negative cancel each other out) so the equation will now look like this: 3r=45

Then divide 3 on both sides (multiplication and division also cancel each other out), then the equation looks like this: r=15

And so, Raul is 15 years old.
