Answer:

Step-by-step explanation:

Let's assume that it is rational , so this number can be represented as

$\Large \boldsymbol{}\bf \dfrac{p^{^/is \ an \ integer}}{q^{ / natural}} -irreducible \ \ fraction$

<h3> $\Large \boldsymbol{}\bf \dfrac{1 ^{/ an \ integer }}{\sqrt{2}^{ / not \ \ integer } }$ -Since the denominator is not a natural number then the 1/√2 is respectively an irrational number</h3>

What is 2x - 3 = -x + 3

BARSIC [14]

<span>Simplifying 2x + -3 = -1x + 3
Reorder the terms: -3 + 2x = -1x + 3
Reorder the terms: -3 + 2x = 3 + -1x Solving -3 + 2x = 3 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right. Add 'x' to each side of the equation. -3 + 2x + x = 3 + -1x + x
Combine like terms: 2x + x = 3x -3 + 3x = 3 + -1x + x
Combine like terms: -1x + x = 0 -3 + 3x = 3 + 0 -3 + 3x = 3
Add '3' to each side of the equation. -3 + 3 + 3x = 3 + 3
Combine like terms: -3 + 3 = 0 0 + 3x = 3 + 3 3x = 3 + 3
Combine like terms: 3 + 3 = 6 3x = 6
Divide each side by '3'. x = 2
Simplifying x = 2

answer x=2
