-5a + b = 2 AND -a - 5b = 0 -5a + b = 2 b = 2 + 5a *using above -a - 5b = 0 -a - 5(2 + 5a) = 0 -a - 10 - 25a = 0 -26a = 10 a = 10/-26 *using 'a' value 5a + b = 2 5(10/-26) + b = 2 -25/13 -2 = -b b = 51/13 Therefore a = 10/-26 b = 51/13
it think ot is 5(a+b)
10a + 5b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
two like terms will always have the same alphabet for example: 3a and 5a are like but 3a and 5b are not
