We have to add the equations in a clever way such that one of the variables cancels out. If you multiply the top one with 3 and the bottom one with 2, you cancel x. Like this:
3(2x+3y)=3*6 => 6x + 9y = 18
2(-3x+5y)=2*10 => -6x + 10y = 20
9y + 10y = 38 => 19y = 38 => y=2
If y=2 then 2x + 6 = 6 => x=0
The pair (0,2) is a solution.
Answer:
<h3>
2642km</h3>
Step-by-step explanation:
Given the map coordinates o a bird during travel from Vermont at cordinate (63,45) toto Venezuela at map coordinates (67,10). In order to know how far the bird has travelled, we need to find the distance between the two coordinates first using the formula;
D = 
Given x₁ = 63, y₁ = 45, x₂ = 67, y₂ = 10

If each map coordinate represents 75 kilometers, then the birds distance in km will be 75*35.2278 = 2642.087km
Hence the birds distance in km will be 2642km to the nearest kilometers
You have to show finding the square root of it ______ ___ __
√144x^2 + √225 = √0
which will give you 12x+15=0
12x=15
x=5/4
