equation with variables
my answer isnt jiving...is it possible the issue is negative sign?
the equation is: 3x-4y=8
then i take 0 for x and 2 for y
what i did was : 3(0)-4(2) =8 0-8=8 is false...unless when i multiply -4(2) because its part of an equation when the 2 comes out of the parentheses its a positive?
