Let's try all the answers with the above equation
a) 4 as p and -4 as q
4 - 4 = 8? INCORRECT
b) 10 as p and 1 as q
10 - 1 = 8? INCORRECT
c) -4 as p and 4 as q
-4 - 4 = 8? INCORRECT
d) 11 as p and 3 as q
11 - 3 = 8? correct
Solve for the first variable in one the equations then substitute the result into the other equation so the answer is (2,5)
90
55.8 /? = 62/100
55.8 x 100= 62 x ?
5580=62 x ?
5580/62 = ?
?=90
