5x-3 =2x+15 Someone pls help for geometry
1 answer:
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>You might be interested in
The division of the polynomial 9x² - 6x - 8 by the polynomial 3x + 2 gives a quotient of 3x - 4 with no remainder
<h3>How to carry out the long division?</h3>The given parameters are:
- Dividend = 9x² - 6x - 8
- Divisor = 3x + 2
To carry out the division, we continue dividing the leading term of the dividend by the leading term of the divisor
At the end of each division step, the quotient is multiplied by the divisor and the result of the product is subtracted from the dividend.
Using the above step, the result of the division is:
Quotient = 3x - 4
Remainder = 0
