Question

SOLVE FOR Y : a) 0.25(4y-3)=0.05(10y-9)

Answer 1

Answer:

Step-by-step explanation:

0.25(4y-3)=0.05(10y-9)

Y-0.75=0.5y-0.45

0.5y=0.30

Therefore y=1.2

Answer 2

Step-by-step explanation:

0.25(4y-3)=0.05(10y-9)

$\frac{25}{100} (4y - 3) = \frac{5}{100} (10y - 9) \\ \\ 25(4y - 3) = 5(10y - 9) \\ \\ 100y - 75 = 50y - 45 \\ \\ 100y - 50y = - 45 + 75 \\ \\ 50y \: = 30 \\ \\ y = \frac{30}{50} \\ \\ y = \frac{3}{5}$

y=0.6
