HELP ME ASAP 1. Given the formula for The Gas Law: PV = nRT. Katie tried to solve for the V variable in order to solve a problem. She rearranged the formula so that V = PnRT. Determine if Katie solved the equation correctly. If not, describe what mistake she made and solve the equation for V and justify your steps.

2.Construct an equation for the expression: -2 times a number increased by 6 is 12. Show the solution to the equation and prove your solution to be true through your work.

3.Construct and describe a real-world situation that can be modeled by the equation 12x = 96. Solve the equation and explain what the solution means in this situation.
