One- and Two-Step Equations flashcards

Question 1

What does it mean to isolate the variable in an equation?

Accepted Answer

To isolate the variable means to rewrite the equation so the variable is alone on one side (like $x=$ something), using operations that keep both sides equal.

Question 2

Solve the two-step equation $3x+5=26$.

Accepted Answer

$x=7$

Question 3

Solve the equation with fractions $\frac{2}{3}x=10$.

Accepted Answer

$x=15$ (multiply both sides by the reciprocal $\frac{3}{2}$).
