Introduction

In algebra, solving for a variable in a linear equation is a fundamental concept. The equation Ax+By=CA x + B y = C is a linear equation in two variables, xx and yy. In this article, we will focus on solving for the variable BB in the equation Ax+By=CA x + B y = C. We will use algebraic methods to isolate the variable BB and find its value.

Understanding the Equation

The equation Ax+By=CA x + B y = C is a linear equation in two variables, xx and yy. The coefficients of the variables are AA and BB, and the constant term is CC. To solve for BB, we need to isolate the variable BB on one side of the equation.

Isolating the Variable BB

To isolate the variable BB, we can use algebraic methods such as addition, subtraction, multiplication, and division. We can start by subtracting the term AxA x from both sides of the equation to get:

By=C−AxB y = C - A x

Next, we can divide both sides of the equation by yy to get:

B=C−AxyB = \frac{C - A x}{y}

Simplifying the Expression

The expression C−Axy\frac{C - A x}{y} is the solution to the equation Ax+By=CA x + B y = C. However, we can simplify this expression further by factoring out the common term yy from the numerator:

B=Cy−AxyB = \frac{C}{y} - \frac{A x}{y}

Interpreting the Results

The solution to the equation Ax+By=CA x + B y = C is the expression Cy−Axy\frac{C}{y} - \frac{A x}{y}. This expression represents the value of the variable BB in terms of the other variables xx, yy, and CC. We can use this expression to find the value of BB for any given values of xx, yy, and CC.

Example

Suppose we have the equation 2x+3y=52 x + 3 y = 5. We can use the expression Cy−Axy\frac{C}{y} - \frac{A x}{y} to solve for the variable BB. Plugging in the values A=2A = 2, x=1x = 1, y=2y = 2, and C=5C = 5, we get:

B=52−2(1)2B = \frac{5}{2} - \frac{2(1)}{2}

Simplifying the expression, we get:

B=52−1B = \frac{5}{2} - 1

B=32B = \frac{3}{2}

Therefore, the value of the variable BB is 32\frac{3}{2}.

Conclusion

Solving for the variable BB in the equation Ax+By=CA x + B y = C involves using algebraic methods to isolate the variable BB on one side of the equation. We can use the expression Cy−Axy\frac{C}{y} - \frac{A x}{y} to find the value of BB for any given values of xx, yy, and CC. By following the steps outlined in this article, we can solve for the variable BB and find its value.
