Question

60 A + 24b and 36a- 18b = -6 find the a and b
values

Answer 1

60A + 24 B = 0
dividing by 4 to above equation to simplify it
we get 15A + 6 B = 0...@1

36A - 18 B = -6
dividing by 3 to above equation to simplify it
we get 13A - 6 B = -2 ...@2

Adding @1 and @2
we get 28 A = -2
A= -2/28= -1/14
putting the value of A in @1
we get 15A + 6B = 0
15(-1/14) + 6B = 0
B = -14/15×6
B=-84/16=-21/4
Hence solved
