If 29 x 3Y 9 35 x 3Y 5 find the value of Y - JAMB Mathematics 1999 Question
If 29 x (3Y)9 = 35 x (3Y)5, find the value of Y.
A
4
B
3
C
2
D
1
correct option: d
The correct answer is 1.
PROVE==> (2x90) (3x90 + Yx91) = (3x50)(3x50 + Yx51).
You multiply to get 2(3+9Y)=3(3+5Y).
You further multiply to get 6+18Y=9+15Y. ==>
Collect like terms 18Y-15Y=9-6.
3Y/3=3/3.
Y=1
