Distribute 2: Distribute the 2 across the parentheses.We need to apply the distributive property to remove the parentheses. This means we multiply 2 by each term inside the parentheses.2(f−12) becomes 2f−2×12, which simplifies to 2f−24.
Set up equation: Set up the simplified equation.After distributing, our equation is now 2f−24=10.
Add 24: Add 24 to both sides of the equation to isolate the term with the variable f. We want to get f by itself on one side of the equation, so we need to undo the subtraction of 24. To do this, we add 24 to both sides of the equation. 2f−24+24=10+24 simplifies to 2f=34.
Divide by 2: Divide both sides of the equation by 2 to solve for f. To isolate f, we divide both sides of the equation by 2. 22f=234 simplifies to f=17.
