Lets say there are 5 sea urchins. The number of sea horses is times 4. So 5 times 4 is 25.
So there are 25 sea urchins!
First, subtract bh from both sides and cancel. Then, divide both sides by h and cancel. Finally, r= 25-bh/ h
Basically you have to solve for the value of Y when x= 4
So you have -5y= 11 - 2x
y = -11/5 + 2/5x
therefore when x = 4 , y = -3/5
Answer:
x = -7/9; y = 4/3.
Step-by-step explanation:
I will assume that the top equation is 6x + 2y = -2, and the bottom one is 3x - 2y = -5.
If you add the two...
(6x + 3x) + (2y + (-2y)) = (-2 + (-5))
9x + 0 = -7
9x = -7
x = -7/9
6(-7/9) + 2y = -2
-42/9 + 2y = -18/9
2y = 24/9
y = 24/18
y = 12/9
y = 4/3
