Simplify it to 6v=12
divied 12 by 6
v=2
Answer: exact form: y= -23/4
Step-by-step explanation: move all the terms that doesn’t contain “y” to the right side and solve.
You have to swap to (x,y) to (y,x) and make the y negative so it would be (-y,x) and since it’s counterclockwise it would be in the 4th quadrant
Answer:
y = 15
x = 43
Step-by-step explanation:
this is giving us a system of equations because we know two things:
x + y = 58
x - y = 28
take the second equation and format it where you have simplified it for one variable:
x = 28 + y
(we did this by adding y to both sides)
now substitute this new value of x into the <em>first </em>equation:
28 + y + y = 58
simplify this to get 2y = 30
divide both sides by 2: y = 15
now substitute your new value of y into the <em>second </em>equation:
x = 28 + 15
x = 43
