Solving Two-Step Equations Effectively

What is the primary goal when solving two-step equations?

• To get the variable by itself

• To eliminate all fractions

• To make both sides equal zero

• To simplify the equation to one step

Why is it generally better to eliminate addition or subtraction first in two-step equations?

• It simplifies the multiplication

• It makes the equation more complex

• It avoids creating fractions

• It is always the first step in any equation

In the example where 6x + 9 = 39, what is the first step to isolate x?

• Multiply both sides by 6

• Add 9 to both sides

• Subtract 9 from both sides

• Divide both sides by 6

• 1

• -1

In the equation c/5 + 2 = 7, what is the first step to isolate c?

• Multiply both sides by 5

• Subtract 2 from both sides

• Add 2 to both sides

• Divide both sides by 5

How do you eliminate a fraction in an equation like x/3 = 4?

• Add the reciprocal of the fraction

• Divide by the fraction

• Subtract the fraction

• Multiply by the reciprocal of the fraction

What is the result of solving the equation 5x + 30 = 25?
