2*4-2*x/9=6*3.4/2
X=?

a+bi=2+5i a^2-b=4-25 a^2-b=-21 a^2=b-21
a in terms of b: a = root(b-21)
b in terms of a: b = (a^2)+21
2*4-2*x/9=6*3.4/2 8-2x/9=10.2 -2x/9=2.2 -2x=19.8 x=-9.9
cos(47) = 2xy + 2x not enough information, but can solve for y in terms of x 0.68 = 2x(y+1) 0.34 = xy+x y = 0.34/x
x^2 - 4x + c not an equation |
