Answer: 
Step-by-step explanation:
By definition, when you multiply two factors the result is known as "Product".
In this case you have to solve the following multiplication:

The first factor is already written in Standard form, but the second one is not written in Standard form.
Then, you need to rewrite it in numbers:

Therefore, the product is:

9/12 divide by 3 equals 3/4
9/12 x 2 = 18/24
this is the only two things I can show you I hope this helps
If we multiply the bottom equation by 2 and move x to the right, it becomes:
4y = 2x-38
Now we can substitute it for the 4y in the top equation:
3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3
Then 4y = 2*3-38 => y = -8
So the solution is (3,-8)
Step-by-step explanation:
let jon age be x
dad age is 2 of x i.e 2x
grandpa age is 7 + 3(x)
The sum of jon dad and grandpa age is 145 i.e
x + 2x + (7+3x) = 145
3x +. 7 + 3x = 145
6x = 145- 7
6x = 138
divide both sides by 6
x = 23
jon age is 23
while
grandpa age is
7 + 3(x)
7 + 3(23)
7 + 69
76.
