Answer:
<u>Solved for y:</u> 
<u>Solved for x:</u> 
Step-by-step explanation:
Solving for y
<u>Step 1: Subtract 5x from both sides</u>


<u>Step 2: Divide both sides by -6</u>


Solving for x
<u>Step 3: Add 6y to both sides</u>


<u>Step 4: Divide both sides by 5</u>


C) 12V2
12^2 + 12^2 = c^2
144 + 144 = 288
V288 = 12V2
Multiply the previous number by 4.
Y=n*4
