Difficult Solve For X Problems
There are lots of strategies we can use to solve equations Let s explore some different ways to solve equations and inequalities We ll also see what it takes for an equation to have no solution or infinite solutions Here is a set of practice problems to accompany the Linear Equations section of the Solving Equations and Inequalities chapter of the notes for Paul Dawkins Algebra course at Lamar University.
To solve for x in fractions we have to eliminate the denominator by cross multiplication and then solve for x For example x 4 1 2 5 2 2x 4 8 5 2 By doing cross multiplication we get 2 2x 4 8 5 4x 8 40 4x 40 8 4x 32 x 32 4 x 8 How Do You Solve for x for the Equation 4x 2 8 Practice the different solve for x type of questions using this worksheet - choose from factorising, completing the square, inequalities questions, simultaneous equations, algebraic fractions, exponential equations and story sums. Lots of all the different types which is great for homework or revision before exams.
