Question

Consider this system of equations.

-20y + 42x = 28
20y - 42x = -28

Would this be infinite solutions or no solutions?

Answer 1

@Nnesha

Answer 2

Infinite

Answer 3

try to solve the equations
solve for x and y

if you get x=something ,, y=something then there is a solution
if you get equal sides at the end then infinite many solution
something like 2=3 would be no solution bec both sides aren't equal

Answer 4

This equations are the same with scalar ( -1 )

Answer 5

As Nnesha said or you could use matrix rank for more complex equations

Answer 6

I would get 0y + 0x = 0.

Answer 7

okay 0 times y = ?
0 times x=?

Answer 8

both of them would equal to 0 ?

Answer 9

yes right
