Introduction

In algebra, solving for x is a crucial step in understanding and manipulating equations. It involves isolating the variable x on one side of the equation, while keeping the other variables on the other side. In this article, we will explore two different algebraic equations and learn how to solve for x in each of them.

Equation (a): Solving for x in r5x=tr - 5x = t

The first equation we will solve is r5x=tr - 5x = t. To solve for x, we need to isolate x on one side of the equation. We can start by adding 5x5x to both sides of the equation, which will eliminate the negative term.

r - 5x + 5x = t + 5x

This simplifies to:

r = t + 5x

Next, we can subtract tt from both sides of the equation to get:

r - t = 5x

Finally, we can divide both sides of the equation by 55 to solve for x:

x = \frac{r - t}{5}

However, the original problem statement asks us to solve for x in the equation r5x=tr - 5x = t. To match this, we can multiply both sides of the equation by 1-1:

-1(r - 5x) = -1t

This simplifies to:

- r + 5x = -t

Next, we can add rr to both sides of the equation to get:

5x = r - t

Finally, we can divide both sides of the equation by 55 to solve for x:

x = \frac{t - r}{-5}

Equation (b): Solving for x in m+xn=pm + \frac{x}{n} = p

The second equation we will solve is m+xn=pm + \frac{x}{n} = p. To solve for x, we need to isolate x on one side of the equation. We can start by subtracting mm from both sides of the equation, which will eliminate the constant term.

m + \frac{x}{n} - m = p - m

This simplifies to:

\frac{x}{n} = p - m

Next, we can multiply both sides of the equation by nn to get:

x = n(p - m)

However, the original problem statement asks us to solve for x in the equation m+xn=pm + \frac{x}{n} = p. To match this, we can multiply both sides of the equation by nn:

n(m + \frac{x}{n}) = n(p)

This simplifies to:

nm + x = np

Next, we can subtract nmnm from both sides of the equation to get:

x = np - nm

Finally, we can factor out mm from the right-hand side of the equation to get:

x = m(n - 1)p

However, this is not the solution we are looking for. To solve for x, we need to isolate x on one side of the equation. We can start by subtracting mm from both sides of the equation, which will eliminate the constant term.

m + \frac{x}{n} - m = p - m

This simplifies to:

\frac{x}{n} = p - m

Next, we can multiply both sides of the equation by nn to get:

x = n(p - m)

However, we can simplify this further by distributing the nn to the terms inside the parentheses:

x = np - nm

This is the solution we are looking for.
