How do I solve for X in: 1.4460(x) + 1.3329(1-x) = 1.4255
OK, let's multiply everything out. We start with
1.4460(x) + 1.3329(1 - x) = 1.4255 now multiply out the (1 - x) bracket. This gives us,
1.446.x + 1.3329 - 1.3329.x = 1.4255 put the x-terms together on one side, and the constant values on the other side.
1.446.x - 1.3329.x = 1.4225 - 1.3329 take out a fsctor if x from the two terms on the lhs.
(1.446 - 1.3229).x = 1.4225 - 1.3229 now do the arithmetic
0.1431.x = 0.0996 divide both sides by 0.1431
x = 0.0996 / 0.1431
x = 0.69601677
Answer: x = 0.6960 to 4 dp
