x(.6917)+(1.0318x)(.3083)=63.546
Solve for x

suppose you had
4x + 3(7x) = 55
I am sure you could solve that.
now follow the same steps for your equation. 
7.93?

use your calculator to see if it works for your given equation.

By the "just  look  at  it " theorem, I can see that your solution cannot possible work
your answer of 7.93 is appr 8
.69..(8) is about 5.6
1.3...(8)(.3...) is about 1/3 of 8 or about 2.7
5.6 +2.7 ≠ 63.5...
Give it another serious try 
62.92?
