can someone help me solve the equation below the exercise is about demand and supply equilibrium equation.

GIVEN: P 0+60s; Qs 30 1. Solve for P after a P30.00 specific tax was imposed by the Government. Show your solution. 2. A 25% indirect tax is being collected by the government. Solve for Price. 3. Reflect in a single graph Nos. 1 and 2. 4. With Qd = 400- 20 P and Qs = -20 + 10P 1. SOLVE for the Equilibrium Price and Quantity 2. Show the equations in a table reflecting Qd and Qs. 3. Reflect in a graph the Demand and Supply Equation
