EXPLANATION
Given the system of equations;
(1) 1.70p - 0.34q = 0
(2) 0.17(q+1) - 0.85(p-1) = 0
Aplying the distributive property in (2):
(2) 0.17q + 0.17 - 0.85p +0.85 = 0
Isolating p in (1):
1.70p = 0.34q
Dividing both sides by 1.7:
p=0.34q/1.70
Simplifying:
p=0.2q
Substituting p=0.2 in (2):
(2) 0.17q + 0.17 -0.85(0.2)q + 0.85 = 0
Multiplying like terms:
(2) 0.17q + 0.17 -0.17q + 0.85 = 0
Adding like terms:
