We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144
-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
The answer should be either 2.5 x 10^4 or 2.1 x 10^4.
But I feel 2.5 x 10^4 is a better estimate.
Hope it helped :))

Answer:
Step-by-step explanation:
In order to find the angle θ, in <u>radians</u>, whose<u> tangent</u> is 
you have to follow those steps
Step 1
Using a<u> calculator</u>
Find the angle θ
Remember that
the angle θ belong to the second quadrant
so
Angle θ=
Step 2
Convert degrees to <u>radians</u>
we know that
therefore
the answer is
the angle θ is
