Answer:

Option D. is the answer.

Step-by-step explanation:

The given statement is \frac{a}{b}+\frac{c}{d}=\frac{a+c}{b+d}

Now we have to find a counter example from the given options that the statement is False.

A. a = 3, b = 5, c = -3, d = 5

\frac{a}{b}+\frac{c}{d}=\frac{a+c}{b+d}=\frac{3}{5}+\frac{-3}{5}=\frac{3-3}{5+5}

0 = 0

So the given statement is true.

B. a = 0, b = 4, c = 0, d= 9

\frac{a}{b}+\frac{c}{d}=\frac{a+c}{b+d}

0 + 0 = 0

So for this example the given statement is true.

C. a = -2, b = 1, c = 2, d = 1

\frac{a}{b}+\frac{c}{d}=\frac{a+c}{b+d}

\frac{-2}{1}+\frac{2}{1}=\frac{-2+2}{1+1}

0 = 0

Statement is true for these values.

D. a = 1, b = 2, c = 1, d = 2

\frac{a}{b}+\frac{c}{d}=\frac{a+c}{b+d}

\frac{1}{2}+\frac{1}{2}=\frac{1+1}{2+2}

1=\frac{1}{2}

Therefore, for these values of a, b, c and d, the given statement is False.

Option D. is the answer.

Mazyrski [523]

5w + 9z = 2z + 3w \\ 5w - 3w = 2z - 9z \\ 2w =  - 7z \\ w =  \frac{ - 7z}{2}
The answer is w = -7z/2
