Simplifying 7(-13) + -1(4(-13) + -49) = 0 Multiply 7 * -13 -91 + -1(4(-13) + -49) = 0 Multiply 4 * -13 -91 + -1(-52 + -49) = 0 Combine like terms: -52 + -49 = -101 -91 + -1(-101) = 0 Multiply -1 * -101 -91 + 101 = 0 Combine like terms: -91 + 101 = 10 10 = 0 Solving 10 = 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.
