Answer:
1. x = - 1 -y over 2
2. x = -4(2+y) over 3
Step-by-step explanation:

Like fractions are fractions with the same <em>denominator</em>. They are not necessary the same value.
Answer:
we know that,
y-y1=m(x-x1)
or, y-1=-3(x-5)
or, y-1=15-3x
or 3x+y-16=0 is the required equation
Answer: Using the proportions between the segments, the area of the triangles are:
1. Area of triangle ADC is 25 in^2.
2. Area of triangle BDC is 15 in^2.
3. Area of triangle CDE is 12 in^2.
