How to Solving One-Step Equations?
Equations, where one math operation is acting on the variable, can be solved in one step. The trick is to get the variable x by itself - isolate the variable.The following 4 equations involve one math operation.x+ 2 = 6x-2 = 62x = 6x/2 = 6(2x means 2 multiplied times x)In the above examples, x is the variable. The math operations are: 1.) add, 2.) subtract, 3.) multiply, and 4.) divide. Addition Equations : To solve for addition equations, subtract the number being added to x on both sides of the equation.Example: Solve for x in the equation x + 5 = 13.x + 5 = 13 x + 5 - 5 = 13 - 5 Subtract five from both sides.x = 8 Simplify.8 + 5 = 13 Check the answer.
Subtraction Equations : To solve for subtraction equations, add the number being subtracted from x on both sides of the equation.Example: Solve for x in the equation x - 3 = 19.x - 3 = 19 x - 3 + 3 = 19 + 3 Add 3 to both sides.x = 22 Simplify.22 - 3 = 19 Check the answer.
Implicit Differentiation : To this instance we've done quite a few derivatives, however they have all been derivatives of function of the form y = f ( x ) . Unluckily not all
1. A machine comprises of three transformers A, B and C. Such machine may operate if at least 2 transformers are working. The probability of each transformer working is given as di
For this point we've only looked as solving particular differential equations. Though, many "real life" situations are governed through a system of differential equations. See the
Differentiate following functions. (a) f ( x ) = 15x 100 - 3x 12 + 5x - 46 (b) h ( x ) = x π - x √2 Solution (a) f ( x ) = 15x 100 - 3x 12 + 5x - 46 I
A solution to a differential equation at an interval α Illustration 1: Show that y(x) = x -3/2 is a solution to 4x 2 y′′ + 12xy′ + 3 y = 0 for x > 0. Solution : We'll
