No, you can only simplify an expression. To solve for a variable, it must be in an equation.

It is: x/8.4 times 8.4 = x

Write an expression consisting of up to three terms:One term in which the key variable is squared,one term with a multiple of the variable, anda constant.The first of these MUST be present. The three terms must be added or subtracted.

You must substitute values for the variable.

To simplify an expression you must combine the variables and the constants. Then write the simplified version of the expression so that the expression isn't solved, just simplified. 1a+2(a+5)=2a+7

Evaluate the criteria before executing the conditional expression. In pseudocode:result1 = evaluate( criteria1 );result2 = evaluate( criteria2 );if( result1 && result2 ) initiate_event;Note that this is not the same as the following:if( evaluate( criteria1 ) && evaluate( criteria2 )) initiate_event;If the evaluation of criteria1 fails for any reason, then the whole expression fails and criteria2 is never evaluated. so if the evaluations must be done independently of each other, then they must be done prior to the conditional expression, storing the results for use in the conditional expression.

"Simplify" means to make something simpler. For example, most people would agree that 3x is simpler than x + x + x. "Simplify" is something you do with an expression. However, simplifying things can also help in solving equations.To "solve" means to find the value or values of the variable or variables, that make an equation true. For example, if you have the equation 2x + 1 = 7, solving it means figuring out what value "x" must have, in this case 3, to make the equation true.

19 - 4 * 2 + 8 = 19 - 8 + 8 = 19 The multiplication must be done first: remember BIDMAS/PIDMAS/BODMAS/PODMAS
