Answer:
C.4x-3y=36
Step-by-step explanation:
we are given
We can see that all options do not have denominator
So, firstly we will get rid of denominators
we know that LCD of 2 and 3 is 6
so, we will multiply both sides by 6
and we get
now, we can simplify it
so,
Option-C
Answer:
x = [-b +-sq root (b^2 -4ac)] / 2a a=2 b=-2 c=3
x = [--2 +- sq root(4 - 4*2*3)] / 2*2
x = [2 +- sq root (-20)] / 4] / 4
x1 = 2 + 4.472135955 i / 4
x1 = .5 + 1.1180339887i
x2 = 2 - 4.472135955 i / 4
x2 = .5 - 1.1180339887i
