For what values of y:
Whitepunk [10]

Answer:

y > \frac{3}{17}

Step-by-step explanation:

To solve this problem, simply set the binomial, 5y - 1 as greater than \frac{3y - 1}{4}, and solve for the value of y as you would solve an equation.

Thus:

5y - 1 > \frac{3y - 1}{4}

Multiply both sides by 4

4(5y - 1) > \frac{3y - 1}{4}*4

4*5y - 4*1 > 3y - 1

20y - 4 > 3y - 1

Subtract 3y from both sides

20y - 4 - 3y > 3y - 1 - 3y

17y - 4 > -1

Add 4 to both sides

17y - 4 + 4 > -1 + 4

17y > 3

Divide both sides by 17

\frac{17y}{17} > \frac{3}{17}

y > \frac{3}{17}

Therefore, the value of y that will make the binomial 5y - 1 greater than \frac{3y - 1}{4} is y > \frac{3}{17}.
