Equation Solving Fraction Variable on One Side

To "get rid" of a fraction in an equation you need to multiply by...

• The Numerator

• The Denominator

• The Reciprocal

• Zero

What is the first step you would do to solve the following problem (x-11)/8 = 13

• Multiply both sides by 8

• Add 11 to both sides

• Divide both sides by 8

• Subtract 11 from both sides

When solving equations, you are "isolating" the variable. What does it mean to "isolate" the variable?

• To get the variable alone on one side of the equation?

• To remove the constant from one side of the equation, but leave the coefficient

• To remove the coefficient from one side of the equation, but leave the constant

• To have the variable equal zero

2x - 3 + 4x = 27

• 12

• 4

• 5

• 15

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

8v - 4(v + 8) = 8

• 2

• 10

• 4

• -4 

4.3(v + 2.5) = 8.11 + 4v

• v = -8.8

• v = 4.5

• v = 12

• v = 9

5 ( 2x - 10 ) +2 = 30

• 2.4

• 7.8

• 9

• 6

4 ( 3x - 4 ) = 68

• 7

• 3

• 4

• 9
