I'll do the first two to get you going

# 1



18-4y=-2%286%2B2y%29 Start with the given equation.


18-4y=-12-4y Distribute.


-4y=-12-4y-18 Subtract 18 from both sides.


-4y%2B4y=-12-18 Add 4y to both sides.


0y=-12-18 Combine like terms on the left side.


0y=-30 Combine like terms on the right side.


0=-30 Simplify.


Since this equation is never true for any y value, this means that there are no solutions.



=====================================

# 2



4%288-p%29-1%287-p%29=22 Start with the given equation.


32-4p-7%2Bp=22 Distribute.


-3p%2B25=22 Combine like terms on the left side.


-3p=22-25 Subtract 25 from both sides.


-3p=-3 Combine like terms on the right side.


p=%28-3%29%2F%28-3%29 Divide both sides by -3 to isolate p.


p=1 Reduce.

Answer:

So the answer is p=1
