Compute the given substitutions. Just substitute the expression for the value; you don't need to simplify anything further. Show the intermediate steps of substitution when quantifiers are involved, as we did in class. a) [y + x/x](2x + y > z) b) [z/x](x > 0 → (Vx.x * z > y) ^ x > -1) c) [x/y]Vx.(y > 0 → 3y.y = x) d) [x + 2/x]3x.Vy.x > y

Task 2
Compute the given substitutions. Just
substitute the expression for the value; you
don't need to simplify anything further.
Show the intermediate steps of substitution
when quantifiers are involved, as we did in
class.
a) [y + x/x](2x + y > z)
b) [z/x](x > 0 → (Xx * z > y) ^x> -1)
c) [x/y]Vx.(y > 0 → 3y.y = x)
d) [x + 2/x]3x.Vy.x > y
