Answer:
Step-by-step explanation:
<u>Add:</u>
- 4x² - 2x + 6 + 2x² + 4x - 1 = 6x² + 2x + 5
<u>Subtract:</u>
- 6x² + 2x + 5 - 5x² - 2x + 4 = x² + 9

Answer:
![x=5,y=10](https://tex.z-dn.net/?f=x%3D5%2Cy%3D10)
Step-by-step explanation:
Given:
equation:1
equation:2
Terminating the equations by subtracting equation:2 from equation:1
![4x - 2y -(-x - 2y)= 0-( -25)\\\\ 4x-2y+x+2y=25\\\\5x=25\\\\x=5](https://tex.z-dn.net/?f=4x%20-%202y%20-%28-x%20-%202y%29%3D%200-%28%20-25%29%5C%5C%5C%5C%204x-2y%2Bx%2B2y%3D25%5C%5C%5C%5C5x%3D25%5C%5C%5C%5Cx%3D5)
Putting 'x' in equation :1
![4(5) - 2y = 0\\\\20-2y=0\\\\2y=20\\\\y=10](https://tex.z-dn.net/?f=4%285%29%20-%202y%20%3D%200%5C%5C%5C%5C20-2y%3D0%5C%5C%5C%5C2y%3D20%5C%5C%5C%5Cy%3D10)
![x=5,y=10](https://tex.z-dn.net/?f=x%3D5%2Cy%3D10)
Answer:
The answers are as follows: 12 106 42
Step-by-step explanation:
Given:
Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate
separately and
separately and add them. So we have
.
Now for the second question:
. we would get
Next,
. This could be written as:
. Hence the answers.
