First tell me the expression, then I'll tell you what the first step is in simplifying it.

while (expression) statementdo statement while (expression)In the first form, expression is evaluated. If true, statement is executed and the loop repeats from the evaluation step. In the second form, statement is executed and then expression is evaluated. If true, the loop repeats from the statement step.

Consider consequences.

To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.Ex:Example of Evaluating an Algebraic ExpressionTo evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add. 4.5 + x = 4.5 + 3.2=7.7Solved Example on Evaluating an Algebraic ExpressionEvaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.Choices:A. 12B. 18C. 3D. 6Correct Answer: DSolution:Step 1: p + 3q + 2p - 3q [Original expression.]Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]Step 3: = 3p [Solve within the grouping symbols.]Step 4: = 3 x 2 [Substitute 2 for p.]Step 5: = 6 [Multiply.]

First you have to solve the subtraction and in the next step you will factor it out.

There are two steps to the process: Step-1: Subtract 7 from 6. The answer to this step is -1. Remember that as you proceed to the next step. Now, go on to the next step. Step-2: Take the -1 from the first step, and add 5 to it. The new result is then +4 . The +4 that you have now is the value of the entire original expression.

I suggest that the next step should be identifying "this" expression.

Assume the expression is:4/(x + 2) + 6/(x + 5)Simplify this expression by combining the expressions altogether. Let's go step by step.Step 1: Determine the LCD of the expression.The LCD of the expression is (x + 2)(x + 5). Multiply the top and bottom of each fractional expression by whatever factor the denominator is missing!4/(x + 2) * (x + 5)/(x + 5) + 6/(x + 5) * (x + 2)/(x + 2)Step 2: Combine the expression and simplify.(4(x + 5) + 6(x + 2))/((x + 2)(x + 5))= (4x + 20 + 6x + 12)/((x + 2)(x + 5))= (10x + 32)/((x + 2)(x + 5))

If 14e + 10f = 12f, the first step towards simplifying the expression is subtracting 10f from each side. You therefore have 14e = 2f, which you can divide by 2 to isolate f. Solution: 7e = f

it is a one-step equation
