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??
Answer:
<h2>
y = 4</h2>
Step-by-step explanation:
x + 2y = 10 ⇒ 2y - 10 = -x
-x + 4y = 14
2y - 10 + 4y = 14
6y = 24
y = 4
Answer:
Freezers made up 
= 24% of the appliances sold in January.
Step-by-step explanation:
We have that:
10 + 8 + 12 + 12 + 8 = 50 parts were sold in January.
Freezers made up what part of the appliances sold in January?
12 of those were freezers, so:
Freezers made up = 24% of the appliances sold in January.

corresponding and transversal S
alternate interior and transversal Q
Answer:
x + y = 14
Step-by-step explanation:
Parallel lines have the same slope, so the line's slope will be -1.
Plug this slope and the given point into y = mx + b to find b:
y = mx + b
4 = -1(10) + b
4 = -10 + b
14 = b
Then, plug this and the slope into y = mx + b
y = -x + 14
Then, put this into standard form by moving the x to the other side:
x + y = 14 is the equation in standard form
