Solve for y in the equation 101 x 5 2x - 2 x 4 ... - JAMB Mathematics 1993 Question
Solve for y in the equation 101 x 5(2x - 2) x 4(y - 1) = 1
A
\(\frac{3}{4}\)
B
\(\frac{5}{4}\)
C
\(\frac{2}{3}\)
D
5
correct option: c
10y x 5(2y - 2) x 4(y - 1) = 1
but 10y - (5 x 2)y = 5y x 2y
= (Law of indices)
5y x 2y x 5(2y - 2) x 4(y - 1)
but 10y - (5 x 2)y = 5y x 2y
= (Law of indices)
5y x 2y x 5(2y - 2) x 4(y - 1)
