does anybody know 5x+7y-2

Vocaloid:

Are there any other instructions? As it stands it cannot be simplified further as there are no like terms

ItZjEnNa:

yea what do u plug in for the variables

Spectrum:

Probably hit the minus instead of equal sign, it should be 5x+7y=2, I think.

Spectrum:

Say x=1, then the equation is 5+y=-5

Spectrum:

what can you add to 5 to make it -5?

Spectrum:

@vocaloid please fact-check this, I have never done this kind of problem before.
