70-q-q-2q = 70-4q = 80-4q = 10q=-10/4 = -5/2 = -2.5
Yes, in logic, if p equals q, then q also equals p. This is known as the symmetric property of equality.
1.8q = q - 2.4 1.8q - q = -2.4 0.8q = -2.4 q = -2.4/0.8 q = -2.9999

120% of 80 equals 96. 96/80 = 1.2 = 120%
Q=3310

q = 3
p=3 !
It depends on whether the relationship between p and q is linear, quadratic, cubic etc or more complex. For example, if the relationship is quadratic, the equation q = 2p2 - 5p + 3 meets the requirements of the question and gives the value q = 9 when p = 3.386001 (approx).
