Question

# Solve: and by using elimination method.

Hint:

### Let and now we get the equation in a and b

Now find values of a and b .After finding a and b substitute them in and and find the values of x and y .

## The correct answer is: x=1/2 ; y=1/3

### Ans :- x = 1/2 ; y = 1/3

Explanation :-

Let and now we get the equation in a and b

— eq1

— eq2

Step 1 :- find value of b by eliminating a

Do 3(eq2) - 2(eq1) to eliminate a

∴ b = 6/2 = 3

Step 2 :- find value of a by substituting b=1 in eq1

∴ a = 2

Step 3 :- substitute a and b in and find values of x and y

and y = 1/3 is the solution to the given pair of equations.

During mineral formation, the same chemical compound can beco me different minerals depending on the temperature and pressure at the time of formation. A phase diagram is a graph that shows the conditions that are needed to form each mineral. The graph above is a portion of the phase diagram for aluminosilicates, with the temperature t , in degrees Celsius , on the horizontal axis, and the pressure p , in gigapascals (GPa), on the vertical axis.

An equation of the boundary line between the andalusite and sillimanite regions is approximated by the equation above. What is the meaning of the T-intercept of this line?

**Note;**

A phase diagram represents the different physical states of some substance under different conditions, such as termperature and pressure, graphically. It may seem like a complicated graph but we just needed to focus on the equation of one given line.
