Answer:
The solution is (2,3).
Step-by-step explanation:
Given : Equations 2x+y-7=0,\ 4x-3y+1=02x+y−7=0, 4x−3y+1=0
To find : Draw the following pair of linear equation in two variables and solve?
Solution :
We put different values of x and y,
Let 2x+y-7=02x+y−7=0 ....(1)
x | 0 3.5 1 3
y | 7 0 5 1
Plot the equation, marked by red line.
Let 4x-3y+1=04x−3y+1=0 ....(1)
x | 0 -0.25 1 0.5
y | 0.3 0 1.6 1
Plot the equation, marked by blue line.
The intersection point of both the equation is the solutions of the equations i.e. (2,3).

Step-by-step explanation:
Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. Wikipedia
