Question

# Solve: and

Hint:

### Let 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=-24/91 ; y=-11/91

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

—- eq1

—- eq2

Step 1 :- find value of b by eliminating a

Do eq2 - 3(eq1) to eliminate a

∴ b = -7

Step 2 :- find value of a by substituting b= -7 in eq1

∴ a = -13/5

Step 3 :- substitute a and b in

and

Now let — eq3

—- eq4

Step 4:- finding x by eliminating y

Adding eq3 and eq4 we get

Step 5:- finding y by substituting value of x in eq 3

is the solution to the given pair of equations.

Step 1 :- find value of b by eliminating a

Do eq2 - 3(eq1) to eliminate a

Step 2 :- find value of a by substituting b= -7 in eq1

Step 3 :- substitute a and b in

Step 4:- finding x by eliminating y

Adding eq3 and eq4 we get

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.
