Answer 2

The solution of the given equation is 2

GIVEN:- 10y-0.2 (7-y)=19

TO FIND:- the value of y

SOLUTION:-

$10y-0.2 (7-y)=19$

Brackets imply multiplication. Firstly we'll multiply

$10y-1.4 + 0.2y=19$

Adding y variable

$10.2y - 1.4 = 19$

When we shift any number or variable from one side to another then the sign changes

$10.2y = 19 + 1.4 \\ 10.2y = 20.4$

Dividing both sides by 10.2

$\frac{10.2y}{10.2} = \frac{20.4}{10.2} \\ y = 2$

Hence, the solution of the given equation is 2
