Answer: 4
Step-by-step explanation: To have an equation with no solution you have to get something like 0=1 meaning you have to remove all the variables. In this equation you would distribute to get xy+2y+2x=2x+12+4x where y is the missing number. then combining like terms you get xy+2x+2y=6x+12. Subtracting 2x from both sides you get xy+2y=4x+12. Now to get the variables gone y has to be 4 so that the variables to cancel out. By plugging in 4 you can see this works; 4x+8=4x+12 and by subtracting 4x from both sides you get 8=12 which is not true meaning there is no solution.
Answer: H = 
Step-by-step explanation:
Step 1: Add h to both sides.
hx+x²+h=−h+x+h
hx+x²+h=x
Step 2: Add -x^2 to both sides.
hx+x²+h+−x²=x+−x²
hx+h=−x²+x
Step 3: Factor out variable h.
h(x+1)=−x²+x
Step 4: Divide both sides by x+1
