For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

$\left \{ +{{7x+2y=17} \atop {2x-2y=1}} \right. \\\\9x=18\\x=2$

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

$7x+2y=17\\7(2)+2y=17\\14+2y=17\\2y=3\\y=\frac{3}{2}$

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is $(2,\frac{3}{2}})$ .

Ruppell's Griffons fly up to 37,000 feet. A sperm whale can swim to 3,000 feet below sea level. Using the figure shown as a g

luda_lava [24]

None of these best represents the sea level because the sea level is 0, which is neither negative nor positive and the whale is at 3000 below sea level and the Griffon is at 37,000 above sea level.

This don’t make no sense anyone understand and if u do help plz

1. x = 0 and y = 3

2. x = 2 and y = 7

3. x = 3 and y = 9

4. x = 5 and y = 13
