Which of the following equations have the same solution? Give reasons for your answer that do not depend on solving the equation

topjm [15]

<u>Answer:</u>

A,C and E are equal with 4 as their solution; F and B are equal with 0 as their solution. D is independent.

<u>Solution:</u>

A. $-(7-4x)=9$

Taking off the brackets we get,

$-7+4x=9 \Rightarrow +4x=9+7$

$\Rightarrow 4x=16 \\$

$\Rightarrow x=\frac{16}{4} \Rightarrow 4$

Here x=4 --- (a)

B. $12=-4(-6x-3)$

Multiplying -4 inside we get,

$12=+24x+12 \Rightarrow 12-12=24x$

$\Rightarrow x=0$

Here x=0 --- (b)

C. $5x+34=-2(1-7x)$

Multiplying -2 inside we get,

$5x+34=-2+14x$

Grouping the terms,

$34+2=14x-5x \Rightarrow 36=9x$

$\Rightarrow x=4$

Here x=4 --- (c)

D. $14=-(x-8)$

$\Rightarrow 14=-x+8 \Rightarrow -x=14-8$

$\Rightarrow x=-6$

Here x=-6 --- (d)

E. $-8=-(x+4)$

$\Rightarrow -8=-x-4 \Rightarrow x=8-4$

$\Rightarrow x=4$

Here x=4 --- (e)

F. $x+5=-5x+5$

$\Rightarrow x+5x=5-5$

$6x=0 \Rightarrow x=0$

Here x=0 --- (f)

So, from the above calculations we can conclude that (a), (c) and (e) are equal and (f) and (b) are equal but (d) is independent because it has a different solution.

$a+b+c=180, \text{ }c+e=180 \implies \\ a+b+c=c+e \implies \\ a+b=e\\$

This result is actually true for any exterior angle. The exterior angle of a triangle is equal to the sum of the two remote angles, and above is a short proof of it.

Answer:

$\huge\boxed{\sf \frac{x+3}{x-3}}$

Step-by-step explanation:

$\displaystyle = \frac{x+7}{x^2+4x-21} \div \frac{x+5}{x^2+8x+15} \\\\Apply \ mid-term \ break\\\\= \frac{x+7}{x^2 +7x-3x-21} \div \frac{x+5}{x^2 +3x+5x+15} \\\\= \frac{x+7}{x(x+7)-3(x+7)} \div \frac{x+5}{x(x+3)+5(x+3)} \\\\Taking \ (x+3) \ and \ (x+7) \ common\\\\= \frac{x+7}{(x-3)(x+7)} \div \frac{x+5}{(x+3)(x+5)} \\\\= \frac{1}{x-3} \div \frac{1}{x+3} \\\\= \frac{1}{x-3} * (x+3)\\\\= \frac{x+3}{x-3} \\\\\rule[225]{225}{2}$

Hope this helped!
