Determine which system below will produce infinitely many solutions.

-4x + 6y = 20
4x - 3y = -2

-2x + 4y = 18
4x - 8y = -36

3x - 2y = 5
-6x - 4y = -10

5x - 3y = 12
15x - 9y = 24

Another way(without a calculator) is to look at the eq, in order to have infinitely many solutions the other eq must essentially be the same as the first. (just a multiple)

fibonaccichick666 · Answer

SO to have infinitely many solutions what do the eqs need to represent?

jdoe0001 · Answer

solve each for "y"
that is, set them in slope-intercept form   and simplify them

after simplification... the system that has 2 equations looking the same

meaning, the simplified form of the equation equals the other
it means both equations are the same line

thus producing "infinite" solutions
