Given the numerical equation:

-3 = xy + 7

Solve for x.

Solution:

In order to solve for x, we equate the given numerical equation in terms of.

-3 = xy + 7

Start by transposing 7 on the other side of the equation, note that when transposing a number the sign changes.

  • -3 -7 =xy
  • - 10 = xy
  • Divide both sides by y in order to get the value of x.
  •  
  • - 10/y = xy/y
  • x = -10/y

 

Final answer: x = -10/y
