Answer:
-8,-29
Step-by-step explanation:
a - b = 21 --------------------------Equation 1
5a - 2b = 18 ----------------------Equation 2
From Equation 1, a = 21 + b
Putting the values of a in Equation 2 we get;
5(21 + b) - 2b = 18
105 + 5b - 2b = 18
3b = 18 - 105
b = -87 / 3
b = -29
Putting the values of b in Equation 1 we get;
a = 21 + (-29)
a = 21 - 29
a = -8
