Which is a correct first step in solving 5 2x 8x 3 quizlet?
Which is a correct first step in solving 5 – 2x < 8x – 3? Step 1: Subtract 3 from both sides of the inequality. Step 3: Divide both sides of the inequality by the coefficient of x.
How do you solve equations with fractions and variables?
Solve equations by clearing the Denominators
- Find the least common denominator of all the fractions in the equation.
- Multiply both sides of the equation by that LCD.
- Isolate the variable terms on one side, and the constant terms on the other side.
- Simplify both sides.
Can a linear equation have a fraction?
We need more than two operations to solve a linear equation . If an equation contains fractions, multiply both sides of the equation by the least common denominator (LCD) to clear fractions. …
How do you remove a fraction from an equation?
If you have a fractional coefficient and another term, you can isolate the term with the variable and then multiply both sides by the reciprocal of the fractional coefficient. To clear a fraction from an equation, multiply all of the terms on both sides of the equation by the fraction’s denominator. Solve for the variable.
Which is the best way to solve an equation?
Here are some things we can do: Add or Subtract the same value from both sides Clear out any fractions by Multiplying every term by the bottom parts Divide every term by the same nonzero value Combine Like Terms Factoring Expanding (the opposite of factoring) may also help Recognizing a pattern, such as the difference of squares
Which is not a solution to the equation x = 5?
Example: x − 2 = 4 1 For x=5 we get “5−2=4” which is not true, so x=5 is not a solution. 2 For x=9 we get “9−2=4” which is not true, so x=9 is not a solution. 3 etc
Which is the solution to the equation this equals that?
So an equation is like a statement ” this equals that ” What is a Solution? A Solution is a value we can put in place of a variable (such as x) that makes the equation true. When we put 6 in place of x we get: So x = 6 is a solution. How about other values for x ? For x=5 we get “5−2=4” which is not true, so x=5 is not a solution.
