Question

Q1. wirte four solutions for each of the following equations:

a) πx+y=9

​

Answer 1

Answer:

{1,(9-π)}

{2,(9-2π)}

{-3,(9+3π)}

{(10/π), -1}

Step-by-step explanation:

Given a linear equation such that,

πx + y = 9

We have to write four solutions.

(1) Put x = 1

=> π + y = 9

=> y = 9-π

Solution = {1,(9-π)}

(2) Put x = 2

=> 2π + y = 9

=> y = 9-2π

Solution = {2,(9-2π)}

(3) Put x = -3

=> -3π + y = 9

=> y = 9 + 3π

Solution = {-3,(9+3π)}

(4) Put y = -1

=> πx -1 = 9

=> πx = 9+1

=> πx = 10

=> x = 10/π

Solution = {(10/π), -1}

Hence, four solutions for the given equation are {1,(9-π)} ; {2,(9-2π)} ; {-3,(9+3π)} and {(10/π), -1}
