Final answer:
An equation representing the given situation where the sum of two numbers is 87, and the second is 6 more than twice the first, is x + (2x + 6) = 87.
Step-by-step explanation:
The student's question involves creating an equation based on the given conditions. First, let's define our variables: let the first number be x, so the second number, which is 6 more than twice the first number, will be 2x+6. According to the problem, the sum of these two numbers is 87.
So, we can create the following equation to express this situation:
x + (2x + 6) = 87
Here, we have an equation with one variable, x, which represents the first number. Once solved, it will provide us with both numbers that meet the given conditions.
Equations are mathematical statements that assert the equality of two expressions. They typically contain variables, constants, and mathematical operations like addition, subtraction, multiplication, division, exponents, and more. Equations are solved to find the value(s) of the variables that satisfy the equality.
