Answer» Simplifying5(2r + 6) + -12r = 0Reorder the terms:5(6 + 2r) + -12r = 0(6 * 5 + 2r * 5) + -12r = 0(30 + 10r) + -12r = 0Combine like terms: 10r + -12r = -2r30 + -2r = 0Solving30 + -2r = 0Solving for VARIABLE 'r'.Move all terms CONTAINING r to the left, all other terms to the right.Add '-30' to each SIDE of the equation.30 + -30 + -2r = 0 + -30Combine like terms: 30 + -30 = 00 + -2r = 0 + -30-2r = 0 + -30Combine like terms: 0 + -30 = -30-2r = -30Divide each side by '-2'.r = 15Simplifyingr = 15 |
