Solve the following equation:

[tex]\[ 10x - 5y = 15y - 25x \][/tex]

Given the point [tex]\((2, -)\)[/tex].


Sagot :

Let's solve the given equation step-by-step:

[tex]\[ 10x - 5y = 15y - 25x \][/tex]

1. Start by bringing all terms involving [tex]\(x\)[/tex] to one side and all terms involving [tex]\(y\)[/tex] to the other side. Add [tex]\(25x\)[/tex] to both sides:

[tex]\[ 10x + 25x - 5y = 15y \][/tex]

2. Combine the [tex]\(x\)[/tex] terms on the left side:

[tex]\[ 35x - 5y = 15y \][/tex]

3. Next, add [tex]\(5y\)[/tex] to both sides to bring all the [tex]\(y\)[/tex] terms to the right side:

[tex]\[ 35x = 20y \][/tex]

4. Now, to isolate [tex]\(x\)[/tex], we divide both sides of the equation by 35:

[tex]\[ x = \frac{20y}{35} \][/tex]

5. Simplify the fraction [tex]\(\frac{20y}{35}\)[/tex]:

[tex]\[ x = \frac{4y}{7} \][/tex]

So, the solution to the equation is:

[tex]\[ x = \frac{4y}{7} \][/tex]

This means that for any value of [tex]\(y\)[/tex], [tex]\(x\)[/tex] will be [tex]\(\frac{4}{7}\)[/tex] times that value of [tex]\(y\)[/tex].
