Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
<h3>i) move 2x to the left-hand side and change its sign</h3>5x-2x-3 = 15
<h3>ii) move -3 to the right-hand side and change its sign</h3>5x-2x = 15+3
<h3>iii) collect like terms</h3>3x = 15+3
<h3>iv) add the numbers</h3>3x = 18
<h3>v) divide both sides of the equation by 3</h3>
The order will be IV, III, I, and II.
<h2>Polynomial</h2>Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Given
I. x + 2xyz
II. 9x³y²
III. 18x² + 5ab - 6y
IV. 4 + 3x² - x - 4
The polynomial expressions from least to greatest are based on their degree.
<h3>How to organize?</h3>4 + 3x² - x - 4 is a biquadratic ploynolmial.
18x² + 5ab - 6y is a cubic polynomial.
x + 2xyz is a quadratic polynomial.
9x³y² is a monomial polynomial.
So the order will be IV, III, I, and II.
