What Divided by 9 Equals 43?
Methods
Setting up the problem:
In a problem like this, the “what” means that we’re working with a variable. The most common variable used in math is “x”. So, we could say what number, x, when divided by 9, equals 43?
Solving What Divided by 9 Equals 43
Here’s how you would set up this question as an equation:
x
9
=
43
\frac{x}{9} = 43
9 x = 43
The goal of the problem is to solve for x. To do this we need to change the equation so that x is alone on one side of the equation.In this case, we can do that by multiplying both sides of the equation by 9, resulting in this equation:
x
=
43
∗
9
x = 43*9
x = 43 ∗ 9
Then we simplify and find our answer:
x
=
387
x = 387
x = 387
So, the answer to the question “What divided by 9 equals 43?” is 387.To prove this, we can take the original problem:
x
9
=
43
\frac{x}{9} = 43
9 x = 43
And insert 387 in the place of x:
387
9
=
43
\frac{387}{9} = 43
9 387 = 43
Because this is true, the answer must be correct.
