See the step by step solution

Step by Step Solution

Step 1. Write the given equation.

The given equation is “f78=2”.

Step 2. Solve the given equation.


f78=2 (Given equation)

f78+8=2+8 (Add 8 to both sides)

f7=10 (Simplify)

f7×7=10×7 (Multiply both sides by -7)

f=70 (Simplify)

So, f=70 is the solution of the given equation.

Step 3. Check the obtained solution.

Put f=70 in the given equation f78=2 to get,


Since the value obtained on the left-hand side and right-hand side are equal, the obtained value is indeed a solution of the given equation.
