Answer:
a part of the question is missing
the answer is c because 4(4)+4(5)=36 and 2(4)^2=16 that 36-16=20 and mn (4*5)=20 so that gives you answer c
Answer:
y = 
Step-by-step explanation:
Given
y = 3xy - 1
Collect terms in y on the left side by subtracting 3xy from both sides
y - 3xy = - 1 ← factor out y on the left side
y(1 - 3x) = - 1 ( divide both sides by 1 - 3x
y = 
← multiply numerator/denominator by - 1
y =
1/3−1/2=− -1/6
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1....Complete the multiplication and the equation becomes ....The two fractions now have like denominators so you can subtract the numerators. This fraction cannot be reduced.....and that's how i got the answer
