Question

Express x in terms of y,given that 4x+3y =6.check whether the point (2,-1)is on the given line.

Answer 1

Answer:

As here given ,

4x+3y=6

so the value of x is,

x = 6-3y/4

x= 6+3/4

x = 9/4

Answer 2

Answer:

Given equation is

4x + 3y = 6.....(I)

=> 4x = 6 - 3y

or, x = (6-3y)/4. Hence expressed.

Take LHS of eq. I and put in x= 2 and y = -1

=> 4(2) + 3(-1) = 8 - 3 = 5 ≠ 6

Hence point (2,-1) does not lie on the given line.
