Question

Solve by using cross multiplication method
3p-2q=5; q-1=3p

Answer 1

Answer:

p = -7/3 , q = -6

Step-by-step explanation:

Given equations

3p-2q = 5 => 3p-2q - 5 = 0

q-1=3p => -3p+q -1 = 0

q c p q

-2 -5 3 -2

X X X

1 -1 -3 1

p/(2+5) = q/(15+3)= 1/(3-6)

p/7= q/18=1/-3

p/7= 1/-3 or q/18=1/-3

p = -7/3 or q = 18/-3 = -6

therefore p = -7/3 , q = -6
