Question

Express x, in terms of y, if 3x + 2y = 5,
check whether (1, 1) is a point on the line
represented by the equation 3x + 2y = 5.
​

Answer 1

3x + 2y = 5

3x = 5 - 2y

x = 5-2y/ 3

Yes (1,1) is a point on the line. I.e. is a solution of equation 3x + 2y = 5

As

3×1 + 2×1=5

3+2 = 5

Hence fulfills the condition.

Answer 2

3x+2y=5

3×=5-2y

x=5-2y/3

as

3×1=2×1=5

3+2=5
