x2 + 3x - 1 is an expression, NOT an equation so, as it stands, there is nothing to solve.
If the equation was the above expression = 0, then using the quadratic equation,
x = [-3 ± sqrt(9 + 4*1*1)]/2
= [-3 ± sqrt(13)]/2
= -0.30278 and 3.30278 (to 5 dp)

How do you solve x-1 plus x2-x plus x3-x2 plus x4-x3?
x4 - 1.We can not "solve" this as we have not been told the value of x. However, we can simplify this expression:We have an x and a minus x here which will cancel out. Likewise the x2 and x3 will cancel out with the -x2 and -x3 respectively. This therefore leaves us with just x4 - 1.

Consider the following linear programming problem Max Z equals 3x1 plus 2x2?
Given the limited information in the question, Z is maximised when x1 or x2 (or both) are maximised. There is no trade-off between x1 and x2 to worry about.
