If 4y – 3x = 5, what is the smallest integer value of x for which y>100?
Solution
Correct Answer: Option C
Since 4y - 3x = 5
=>4y = 5 + 3x
=>4y - 5 = 3x
=>3x = 4y - 5
if you look at the equation you will notice that x is directly proportional to y
therefore if we increase the value of y, x is also increases.
If the value of y is smallest then the x is also smallest.
Since y>100
therefore the smallest value of y = 101
therefore the equation is 3x = 4 X 101 - 5
=> 3x = 404 -5
=> x = 399/3
=> x = 133
