To solve a literal equation means to express one variable with respect to the other variables in the equation.
Step-by-step explanation:
1.
Determine which variable you need to isolate. Isolating a variable means getting the variable on one side of an equation by itself.
2.
Use algebra to solve for the desired variable. Use inverse operations to cancel variables on one side of the equation and move them to the other side. 3.
Keep the equation balanced. Whatever you do to one side of the equation, you must also do to the other side
Because since rs Is equal to qr since r is the midpoint of qs. So qr is 8 and because s is the midpoint of the whole line. I multiply it by 2. Giving me 16 for the whole line
