Answer:
(x-3)/y
Step-by-step explanation:
x minus 3 is self explanatory, x - 3.
Then we divide that quantity by y, so we're just putting y under it.
Therefore, we get (x-3)/y
Answer: y=-6
Step by step explanation:
2y-2=-14
2y=-12 (move the negative 2 to the right)
y= -6 (divide both sides by 2)
Your equation is then y=-6
You have the ratios set up but you need to cross multiply everything:
(5x + 10) x 11 = 121 x 10
55x + 110 = 1210
Subtract 110 from both sides:
55x = 1100
Divide both sides by 55:
X = 1100 / 55
X = 20
