Question

4y-2=1/5 solve and check your answer fast​

Answer 1

Step-by-step explanation:

$4y-2=1/5 \\ = > 4y = 2 + (1 \div 5) \\ = > 4y = (10 + 1) \div 5 \\ = > 4y = 11 \div 5 \\ = > y = (11 \div 20)$

CHECKING,

Put y = 11/20 in given eqn.

$lhs = 4y - 2 = 4 \times (11 \div 20) - 2 \\ = (11 \div 5) - 2 \\ = (11 - 10) \div 5 =(1 \div 5) = rhs$

Answer 2

Answer:

Step-by-step explanation:

$4y-2=\frac{1}{5}$

$4y=\frac{1}{5}+\frac{2}{1}$

$4y=\frac{1}{5} +\frac{10}{5}$(lcm)

4y=$\frac{11}{5}$

y=$\frac{11}{5*4}$

y=$\frac{11}{20}$

4*11/20-2=1/5

11/5-2=1/5

1/5=1/5

hence proved
