25 - 4x = 15 - 3x + 10 - x how to solve

Mathematics
1 answer:
Svetlanka [38]3 years ago
4 0

Answer:

Infinite solutions

Step-by-step explanation:

25 - 4x = 15 - 3x + 10 - x

Combine like terms

25-4x = 25 -4x

Add 4x to each side

25-4x+4x = 25 -4x+4x

25 =25

This is always true, so the equation has infinite solutions

The expressions are simplified to 2x and \frac{2}{(x+ 1)(x - 1)}

<h3>How to simply the expressions</h3>

1.

Given the expression;

\frac{8x^2 - 4x}{4x - 2}

Let's factorize the numerator;

\frac{2x( 4x - 2)}{4x - 2}

Factor the common terms, we have;

2x

2. \frac{1}{x-1} - \frac{2}{x} + \frac{1}{x + 1}

Find the Lowest common multiple

\frac{x(x+ 1) - 2 (x+ 1)(x - 1) + x(x-1)}{x(x-1)(x+ 1)}

expand the brackets

\frac{x^2 + x -2(x^2 -x + x -1) + x^2 -x}{x(x-1)(x+ 1)}

\frac{x^2+x - 2x^2 -2 + 2x + 2 + x^2 - x}{x(x+1) (x -1)}

collect like terms

\frac{2x}{x(x+ 1) (x-1)}

Divide common terms

\frac{2}{(x+ 1)(x - 1)}

Thus, the expressions are simplified to 2x and \frac{2}{(x+ 1)(x - 1)}
