What Divided by 18 Equals 7?

Accepted Solution

A:
What Divided by 18 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 18, equals 7? Solving What Divided by 18 Equals 7 Here’s how you would set up this question as an equation: x 18 = 7 \frac{x}{18} = 7 18 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 18, resulting in this equation: x = 7 ∗ 18 x = 7*18 x = 7 ∗ 18 Then we simplify and find our answer: x = 126 x = 126 x = 126 So, the answer to the question “What divided by 18 equals 7?” is 126.To prove this, we can take the original problem: x 18 = 7 \frac{x}{18} = 7 18 x ​ = 7 And insert 126 in the place of x: 126 18 = 7 \frac{126}{18} = 7 18 126 ​ = 7 Because this is true, the answer must be correct.
