Well how many 12's are in 24 (forget the negative sing for a moment). Two right? Well that means multiply 4 by 2 and get 8, but where does that negative sign go? Just add it! It makes it so much easier taking it away and then putting it back. That is a trick for this problem. y=-8 while x=-24 Hoped I helped!
Answer:
The answer is b, which is 3+x+3

Answer: 1), 2) and 5) are equivalent.
Step-by-step explanation:
Since in first expression, 2+x=5 ⇒ x= 5-2= 3⇒x=3
In second expression, x+1=4⇒ x=4-1⇒x=3
In third expression, 9+x=6 ⇒ x=6-9⇒x= -3
in Fourth expression, x+(-4)=7 ⇒ x=7+4 ⇒ x=11
In fifth expression, -5+x=-2⇒ x=-2+5 ⇒x=3
Thus, 1) 2) and 5) expression are giving the same result.
Therefore they are equivalent to each other.
Slope int.: y = mx + b
add y to both sides
3x = 7 + y
Subtract 7
3x - 7 = y
Solution: y = 3x - 7
