What is the first step to solve the equation 9 + x = 21?

Back

Subtract 9 from both sides to isolate x, resulting in x = 12.

Front

What is the formula to find the missing angle in a triangle if two angles are known?

Back

The formula is: Missing Angle = 180 - (Angle1 + Angle2).

Front

How do you isolate the variable h in the equation h - 4 = 397?

Back

Add 4 to both sides of the equation to isolate h, resulting in h = 401.

Front

What does it mean to 'isolate a variable' in an equation?

Back

Isolating a variable means manipulating the equation to get the variable on one side by itself.

Front

What is the importance of understanding one-step equations in real-life applications?

Back
