It is: 4b+16 simplified
6a -12b + 30 = 6 (a - 2b + 5)
is eassy
12b - 5 = 15b + 5 subtract 12b from both sides 12b - 12b - 5 = 15b - 12b + 5 - 5 = 3b + 5 subtract 5 from each side - 5 - 5 = 3b + 5 - 5 - 10 = 3b divide both sides integers by 3 - 10/3 = (3/3)b - 10/3 = b ---------------------check in original equation ( change whole numbers to fractions of common denominations ) 12(-10/3) - 15/3 = 15(-10/3) + 15/3 - 120/3 - 15/3 = - 150/3 + 15/3 - 45 = - 45 checks
