To solve equations effectively in four steps, consider these types: Linear Equations: Isolate the variable by adding or subtracting terms, then divide or multiply to solve. Quadratic Equations: Rearrange to standard form, factor or use the quadratic formula, simplify, and solve for the variable. Rational Equations: Clear the denominators, simplify the resulting equation, isolate the variable, and solve. Exponential Equations: Take the logarithm of both sides, isolate the variable, and simplify to find the solution. Systems of Equations: Use substitution or elimination to reduce the system, isolate one variable, and solve for it.
Step 1 :Do Add-opp(algebraic definition of subtraction)if possible;if your problem has a minus sign Step 2: Combine like terms. Step 3 :Take the opposite of x(the unknown number) Step 4: Do the same to the other side; whatever you do on one side, you must do to the other Step 5 : Check your answer! :D GOOD LUCK ON THIS! C.S.I - Constructing, Solving, Interprettation
x / 5 = (3x - 4) / 7 When solving equations with one rational expression on both sides, cross multiply. 5(3x - 4) = 7x 15x - 20 = 7x 8x - 20 = 0 8x = 20 x = 5 / 2
If 3x -5y = 16 and xy = 7 then by combining both equations into a single quadratic equation and solving it then the points of intersection are at (-5/3, -21/5) and (7, 1)

1. Draw a free-body diagram if applicable. 2. Identify what variables are known and what variables are sought. 3. Identify equations that relate the variables. 4. Do computations. 5. Do a reasonableness check: is the answer reasonable? If not, try solving the problem a different way to see if you get the same solution.

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
The answer will depend on statement 3 5 - whatever that may be!

Let's denote the two numbers as x and y. We can set up a system of equations based on the given information: xy = 20 and x + y = 7. By solving these equations simultaneously, we can find that the two numbers are 5 and 4. This is because 5 * 4 = 20 and 5 + 4 = 9, not 7.
To implement the Runge-Kutta 4(5) method in MATLAB for solving differential equations efficiently, you can use the built-in function ode45. This function automatically selects between the fourth and fifth order Runge-Kutta methods based on the error estimates. Simply define your differential equation as a function and provide it to ode45 along with the initial conditions and the desired time span. MATLAB will then solve the differential equation using the Runge-Kutta 4(5) method and provide the solution efficiently.
