Question

which of the following is not the solution of 2x + 3y = 6. option A 5/ 7. option B 3/5 . option C 7 / 5 . option D 5/3​

Answer 1

option c is the answer .

Solution of a equation satisfies the equation.

Given equation 2x+3y=6...(1)

Let's take option A,  x=3,y=0  

LHS =2×3+3×0=6= RHS

LHS = RHS

Hence, (3,0) is a solution of eq (1)

Option B, x=0,y=2

LHS =2×0+3×2=6= RHS

LHS = RHS

Hence, (0,2) is a solution of eq (1)

Option C, x=−3,y=4

LHS =2(−3)+3(4)=6= RHS

LHS = RHS

Hence, (−3,4) is a solution of eq (1)

Option D, x=1,y=1

LHS =2×1+3×1=5



= RHS

LHS  



= RHS

Hence, (1,1) is not a solution of eq (1)

Hence option D is answer
