Isolate variable f: First, we want to isolate the variable f on one side of the equation. To do this, we can subtract 7f from both sides of the equation to move all the f terms to one side.1+8f−7f=−6+7f−7f
Simplify both sides: Now, we simplify both sides of the equation by combining like terms. 1+f=−6
Solve for f: Next, we want to solve for f by isolating it. We can subtract 1 from both sides of the equation to move the constant term to the other side.1+f−1=−6−1
Perform subtraction: Simplify both sides of the equation by performing the subtraction. f=−7
