write an equation that involves multiplication, contains a variable, and has a solution of 5. then write another equation that has the same solution and includes the same variable and numbers but uses division.

Answers

(1) 2x = 10

(2) x = 10 / 2

Hope this helped!
Let's make it a simple equation, yes?
We'll use the variable x
Equation involving multiplication:
2x=10
We'll solve it to make sure it works. Since the solution has to be five, we'll plug that in for x
2×5=10
10=10
This works, so we can move on.
Equation involving division:
10÷x=2
Again, we'll solve it to make sure it works, plugging in 5 for x
10÷5=2
2=2
This equation works as well.
The two equations are
2x=10
and
10÷x=2
