Question

Which system of equations would have no solution? pls helpp

Answer 1

3x+y=8 and 3x+y=9

Explanation:

Assume these two equations:

a1x+b1y+c1=0

a2x+b2y+c2=0

If (a1/a2) = (b1/b2) ≠ (c1/c2) than those two would have no solution.

In these case, take a look at the last option:

`3x + y = 8 \\ 3x + y = 9`

Re-write 'em as a standard form:

`3x + y - 8 = 0 \\ 3x + y - 9 = 0`

So (a1/a2) = (b1/b2) ≠ (c1/c2) is true here:

`(3)/(3) = (1)/(1) ≠ ( - 8)/( - 9)`

And they do not have any collision point
