8 - 4(x - y) = 2x + 6
8 - 4x + 4y = 2x + 6
-4x - 2x + 4y = 6 - 8
-6x + 4y = -2
6x - 4y = 2 <====
Answer:

Step-by-step explanation:

Rewrite to remove fractions
The denominators in the above expression are 4 and 6.
So, first we take the LCM of 4 and 6

Next, multiply both sides of the equation by this LCM (12)




The last one since there are no solutions
Answer:
Step-by-step explanation:
f(x) = 2(x − 1)² + 3
= 2 ( x² - 2x +1) +3
= 2x² - 4x +2 +3
f(x) = 2x² − 4x + 5 .....standard form.
