Answer: y = (12-x)/(2x)
---------------------------------------------------------------
Work Shown:
2xy+x = 12
2xy+x-x = 12-x ... subtract x from both sides
2xy = 12-x
2xy/2x = (12-x)/(2x) ... divide both sides by 2x to get y all by itself
y = (12-x)/(2x)
Both are functions. Try not to get tripped up on notation of functions. They are they same, just written differently.
f(x) = 3x-10 is the same as 0=3x-10
2x+7y=28 is the same as 2x+7y-28=0
Just one will give you a line and the other will give you a circle. If you are ever unsure, plug them into a graphing calculator and see what you get back.
The equation would be y= 5x + 140
15 - 1 = x thats the answer to the problem thats how you can have the answer
Answer:
2 years
Step-by-step explanation:
Let Principal = 2500
Let Rate = 4%
Let time = x
Simple Interest = Principal x time x rate
200 = 2500 x 4/100 x 'x'
200 = 100x
200/100 = x
2 = x
