Solve For The Indicated Variable.3. Solve For M In The Equation:${ Y = 7m + 6 }$
Solving for the Indicated Variable: A Step-by-Step Guide to Isolating m in the Equation y = 7m + 6
In algebra, solving for a variable means isolating that variable on one side of the equation, while keeping the other side intact. This is a crucial skill to master, as it allows us to find the value of a variable and make predictions about the behavior of a system. In this article, we will focus on solving for the variable m in the equation y = 7m + 6.
Understanding the Equation
Before we dive into solving for m, let's take a closer look at the equation y = 7m + 6. This equation represents a linear relationship between the variables y and m. The coefficient of m, which is 7, tells us how much y changes when m changes by 1 unit. The constant term, which is 6, represents the value of y when m is equal to 0.
Step 1: Subtract 6 from Both Sides
To solve for m, we need to isolate m on one side of the equation. The first step is to subtract 6 from both sides of the equation. This will help us get rid of the constant term and make it easier to isolate m.
y = 7m + 6
Subtracting 6 from both sides gives us:
y - 6 = 7m
Step 2: Divide Both Sides by 7
Now that we have y - 6 on the left-hand side, we can divide both sides of the equation by 7. This will help us get rid of the coefficient of m and isolate m on the left-hand side.
y - 6 = 7m
Dividing both sides by 7 gives us:
(y - 6) / 7 = m
Step 3: Simplify the Equation
Now that we have m isolated on the left-hand side, we can simplify the equation by removing the parentheses.
(y - 6) / 7 = m
Simplifying the equation gives us:
y/7 - 6/7 = m
In this article, we have walked through the steps to solve for the variable m in the equation y = 7m + 6. By subtracting 6 from both sides and dividing both sides by 7, we were able to isolate m on the left-hand side of the equation. This is a crucial skill to master, as it allows us to find the value of a variable and make predictions about the behavior of a system.
