Question

which of these is the solution for the pair of equations X+y=6 and px+qy =r
option :
a) x= 2, y=4
b) x=4 , y=2
c) x=3 , y=2
d) We cannot say for sure as the values of p and q are not known.

​

Answer 1

Answer:

b) x=4, y=2

Step-by-step explanation:

check the point of intersection of the 2 equations..

refer to the image above

Answer 2

Answer:

b) x = 4, y = 2 is the solution of the linear equation of x + y = 6 and px + qy = r.

Step-by-step explanation:

Equations having power 1 to the variables are referred to as linear equations. A single variable example with real numbers for a and b and x as the variable is ax + b = 0.

The term "linear equation" refers to an equation where the greatest power of the variable is one.

There is a lot to learn about linear algebra. Its scope spans the abstract, numerical methods, and applications. Several disciplines, including fractal geometry, differential and difference equations, relativity, archaeology, demography, and many others, require linear algebra.

Given, from the graph

x + y = 6 and px + qy = r intersects at the point x = 4, y = 2.

Hence, x = 4, y = 2 is the solution of the linear equations.
