Answer:
x=7
Step-by-step explanation:
To set up for this answer, we need to set it up as an equation: 2x+12=5x-9.
get the xs on one side and the whole numbers on the other.
that leaves you with 21=3x.
divide by 3 on both sides to get the answer of x=7
Your answer is 0, because the equation for this is y=1. Only vertical lines can have an undefined slope because the x value never changes. Hope this helps.
