please help

vocaloid · Answer

ok, to find the solution to a system of equations, you need to find an x and y value that will make both equations true

vocaloid · Answer

we know that:

y = 7x + 12 and
y = 7x + 2, 

so we know that 7x + 12 = 7x + 2

is there a x value that satisfies the equation?

anonymous · Answer

X is 0

vocaloid · Answer

nope, keep trying

what happens when you subtract 7x from each side? what do you get?

anonymous · Answer

its d
