the sum of 6 and 4 times a number (n) equals 90
would it be 21?
it would indeed.
6+4n=90
To solve the equation given, let's break it down step by step.
First, we'll start by translating the given sentence into an equation. The sentence states that "the sum of 6 and 4 times a number (n) equals 90." Let's represent the unknown number n using a variable, so we can write the equation as:
6 + 4n = 90
Now that we have the equation, we can solve for n:
Step 1: Subtract 6 from both sides of the equation to isolate the term with n:
6 + 4n - 6 = 90 - 6
4n = 84
Step 2: Divide both sides of the equation by 4 to solve for n:
4n/4 = 84/4
n = 21
Therefore, the value of n that satisfies the equation is 21.
