Hello Velina,

You essentially only have to perform one step in order to arrive at the solution to this equation:

x + 7 = 3

x + 7 - 7 = 3 - 7     (Subtract 7 from both sides in order to isolate the x on the left-hand side)

x + 0 = -4   (Remember that 3 - 7 will be a negative number)

x = -4  <== The answer.
