Its actually a trig question, but I'm having trouble with the algebra.
Solve for x
1st equation: x + y = 5 and 2nd equation: x^2/16 + y^2/9 = 1
My work so far...
sub y = x - 5 in to 2nd equation
x^2/16 + (x-5)^2/9 = 1
What do we do from here? Find the common denominator (144) and...
Thanks in advance
