Question

Without actually solving the equations,
determine whether the given simultaneous
equations have unique solution, no solution
or infinitely many solutions.
(i) x + 2 y = 1; 6x = 4y-11​

Answer 1

Answer:

unique solution

Step-by-step explanation:

in linear equation with two variables, if:

coeff. of x in 1st equation : coeff. of x in 2nd equation $\neq$ coeff. of y in 1st equation : coeff. of y in 2nd equation,

then the variables have a unique equation

in the given equations,

1:6 $\neq$ 2 : -4

so it will have a unique solution.
