One-Step Equations Practice Test

Ava saves money and already has $8 in her jar. She wants $20 total, so $x + 8 = 20$. Subtract 8 from both sides to find $x$. What is the value of $x$ in $x + 8 = 20$?

Maya buys 4 notebooks for $3 each at school. She writes the equation $4x = 12$ for the total cost. Divide both sides by 4 to find $x$. Solve for $x$ in $4x = 12$.
