linear equations in two variables

Question 1

check whether (0,2) is a solution of 3x -4y = 8

Answer 1

N0. LHS = 3x0 -4x2 =0-8 = -8
And RHS= 8
LHS is not equal to RHS

Question 2

Is (-2,4) a solution of 5x -2y =-18

Answer 2

yes

Question 3

IS (0,-5) a solution of 3p -7q = 35

Answer 3

yes

Question 4

Find a solution for the equation 3x -5y = -2 ( at x=0, and x= 1)

Answer 4

2/5 and 1

Question 5

Find the value of k in the equation 5x -ky = 12if (3,2) is a solution of it.

Answer 5

5x3 - 2k =12
15-2k =12
-2k = 12 - 15 =-3
k = -3/-2 = 3/2
