Answer:
Step-by-step explanation:
a)For a particular value of x in both the equations,y should have the same value.
Since we see that on x=0.5, y=2.5 and 2 in first and second column respectively and also on x=1, y=2 and 3 in first and second column respectively, so we see that there is a decrease in the value of y in first column but increase in value of y in the second columns, hence these are the two rows between which our solution will lie i.e. x value.
b) x value y=-x+3 Â Â y=2x+1
  x=0.6  y= 2.4    y=2.2
  x=0.7  y=2.3    y=2.4
  x=0.8   y=2.2    y=2.6
  x=0.9   u=2.1    y=2.8
c) On seeing the above table carefully we can see that between values 0.6 and 0.7 the solution will lie.
d) The reasonable approximation for the solution will be x=0.666=0.67
