What Divided by 19 Equals 7?
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 19, equals 7?
Solving What Divided by 19 Equals 7
Here’s how you would set up this question as an equation:
x
19
=
7
\frac{x}{19} = 7
19 x = 7
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 19, resulting in this equation:
x
=
7
∗
19
x = 7*19
x = 7 ∗ 19
Then we simplify and find our answer:
x
=
133
x = 133
x = 133
So, the answer to the question “What divided by 19 equals 7?” is 133.To prove this, we can take the original problem:
x
19
=
7
\frac{x}{19} = 7
19 x = 7
And insert 133 in the place of x:
133
19
=
7
\frac{133}{19} = 7
19 133 = 7
Because this is true, the answer must be correct.
