If it's not what You are looking for type in the equation solver your own equation and let us solve it.

Simplifying (5) * 10 + -1(5) * 13 = 0 Multiply 5 * 10 50 + -1(5) * 13 = 0 Multiply -1 * 5 50 + -5 * 13 = 0 Multiply -5 * 13 50 + -65 = 0 Combine like terms: 50 + -65 = -15 -15 = 0 Solving -15 = 0 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
