Question

Solve the following system of equations in R.

$3x-1\ge 5,x+2>-1$

Answer 1

Consider the first in equation,

$3x-1\ge 53x\ge 5+13x\ge 6x\ge 2...\left(i\right)$

Consider the second in equation,

$x+2>-1x>-1-2x>-3...\left(ii\right)$

From (i) and (ii),$[2,\infty ]$ is the solution set of the simultaneous equations.
