Here's a linear equation in variable x and we have to compute the value of x for the above equation.
Given equation:
So, Let's start solving the above equation:
Move 7 to the Right hand side,
Remember: Inverse of addition is subtraction


Now multiplying 5 in other side because again the inverse of division is multiplication,


And the required value for x is -50. So, we are done....
