For the system below: a.Solve the system by the linear combination method. Show all work carefully. b.Check your answer. a - 2b = 2 a + b - 2(b+3)
my answer;
a + b = 2(b+3) a + b = 2b + 6 a - b = 6 a - 2b = 2 – a - b = 6 ––––––– -b = -4 b = 4 Put this "b" value into the 1st equation: a - 2b = 2 a - 8 = 2 a = 10 Check: 10 – 8 = 2 .......... correct 10 + 4 = 2(4 + 3) .......... correct
