Solution Steps

00:00 Solve
00:03 We want to isolate the unknown Y
00:07 We'll divide by the unknown coefficient to isolate Y
00:19 We'll write division as multiplication by the reciprocal
00:27 We'll use long multiplication for calculation
00:33 And this is the solution to the question

Step-by-Step Solution

We begin by multiplying the simple fraction by y:

15×y=25 \frac{-1}{5}\times y=-25

We then reduce both terms by 15 -\frac{1}{5}

y=2515 y=\frac{-25}{-\frac{1}{5}}

Finally we multiply the fraction by negative 5:

y=25×(5)=125 y=-25\times(-5)=125

Answer

y=125 y=125
