Solving Equations with Variables and Fractions

What is the preferred initial step in solving equations with fractional coefficients?

• Multiply by the least common multiple

• Divide by the greatest common divisor

• Subtract the fractions from each other

• Add the fractions together

What is the least common multiple of 3 and 6 used in the example?

• 3

• 6

• 12

• 18

What is the purpose of multiplying every term by the least common multiple?

• To simplify the equation

• To find the variable's value directly

• To eliminate the fractions

• To increase the equation's complexity

How do you convert a whole number into a fraction for multiplication purposes?

• Multiply by 2

• Divide by 1

• Add 1 to the numerator
