P = 14 Q = 8 R=10

Answer 2

The solution of the linear system are; P = 14 Q = 8 R = 10.

What is linear equation?

Linear equation is equation in which each term has at max one degree.

Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.

The system of equation are;

p + q + r = 32

p - r = 4

2p + q = 36

We need to find the solution of this linear system.

p - r = 4

here, p = 4 +r

Substitute in first equation;

p + q + r = 32

4 + r + q + r = 32

4 + q + 2r = 32

We have already given the value of 2p + q = 36;

here q = 36 - 2p

q = 36 - 2(4 +r)

q = 36 - 8 - 2r

q = 28 - 2r

Now,

The solution of the linear system are; P = 14 Q = 8 R = 10.
