You're meant to make one side of the equation equal 0.
For example, the first problem is
+ 9k = -7
You'd add 7 to both sides, leaving you with
+ 9k +7 =0
And I assume you know how to factor??

Easy.
2x + 3x
2x + 3x
2x ( 1 + 3x / 2x )
2x ( 1 + 1.5 )
2x ( 3 )
6x
or
2x ( 3 )
or
3x ( 2 )
That's it.

Answer:
1. 12
2. Multiply
3. 27
Step-by-step explanation:
These make the most sense because you are supposedly trying to find factors of 12, that multiply to 27. It can't be negative numbers I don't think. And there can't be factors of 27 that multiply to 12.
I'm so sorry if this is incorrect, but I hope it helps!
Answer:
x=1, y=1.
Step-by-step explanation:
From the second equation:
x = 8 - 7y, so substituting for x in the first equation:
3/8(8 - 7y) + 1/3y = 17/24
3 - 21/8 y + 1/3y = 17/24
1/3y - 21/8y = 17/24 - 3
Multiply through by 24:
8y - 21*3 y = 17 - 72
8y - 63y = -55
-55y = -55
y = 1.
And substituting for y in the second equation:
x + 7(1) = 8
x = 8 - 7
x = 1.
