Question

$4y - 2 = \frac{1}{5}$
solve the equation and check the answer

Answer 1

Hi....

4y-2=1/5

4y=1/5+2

4y=11/5

y=11/5*4

y=11/20

Answer 2

$\huge\bold\blue{Solution :}$

$\mathsf{= > 4y = \frac{1}{5} + 2} \\ \\ \mathsf{= > 4y = \frac{1 + 10}{5} }\\ \\ \mathsf{= > 4y \times 5 = 11} \\ \\ \mathsf{= > 20y = 11} \\ \\ \mathsf{= > y = \frac{11}{20} }$

$\underline{\mathsf{Checking}}$

$\mathsf{LHS}$

$\mathsf{ = 4y - 2} \\ \\ \mathsf{= 4 \times \frac{11}{20} - 2 }\\ \\ \mathsf{= \frac{11}{5} - 2} \\ \\ \mathsf{= \frac{11 - 10}{5} }\\ \\ \mathsf{= \frac{1}{5}}$

$\mathsf{RHS}$

$\mathsf{= \frac{1}{5}}$

•°• LHS = RHS

Hence, checked
