Question

which of the following are linear equations 5x²+6xy-4y²=16​

Answer 1

Answer:

A linear equation is an equation for a straight line

example: y=mx+c

Provided equation doesn't match with this. So it's not linear equation.

Step-by-step explanation:

Answer 2

Simplifying

5$x^{2}$ + 6xy + -4$y^{2}$ = 16

Reorder the terms:

6xy + 5$x^{2}$ + -4$y^{2}$= 16

Solving

6xy + 5$x^{2}$ + -4$y^{2}$ = 16

Solving for variable 'x'.

Reorder the terms:

-16 + 6xy + 5$x^{2}$ + -4$y^{2}$ = 16 + -16

Combine like terms: 16 + -16 = 0

-16 + 6xy + 5$x^{2}$ + -4$y^{2}$ = 0

The solution to this equation could not be determined.

A linear equation is an equation for a straight line

example: y=mx+c

The provided equation doesn't match with this. So it's not a linear equation.

Hence, it is not a linear equation.
