Answer: a+b+c=0 and 3a+5b+c=0

Step-by-step explanation:

If you find a solution to these equations, you will find an equation of your line. Please notice that (a,b,c) defines the same line as (ka,kb,kc) and for any non-zero k, and a=b=c=0 defines no line equation at all. Now you can take a=1 and solve for b and c, or take b=1 and solve for a and c, or take c=1 and solve for a and b, at least one of these will work.

Three times the sum of a number and 15 is 24
allsm [11]

Answer:

\huge\boxed{\sf x = -7}

Step-by-step explanation:

<em>Let the number be x </em>

So,

=> The sum of number and 15 is x + 15

=> Three times will be 3(x+15)

<u>Given that</u> it equals 24

<u>So, the given condition is:</u>

3(x+15) = 24

<em>Resolving Parenthesis</em>

3x + 45 = 24

<em>Subtracting 45 to both sides</em>

3x = 24 - 45

3x = -21

<em>Dividing both sides by 3</em>

x = -7
