Question

solve
10y-0.2(7-y)=19​

Answer 1

Answer:

Simplifying

10y + -0.2(7 + -1y) = 19

10y + (7 * -0.2 + -1y * -0.2) = 19

10y + (-1.4 + 0.2y) = 19

Reorder the terms:

-1.4 + 10y + 0.2y = 19

Combine like terms: 10y + 0.2y = 10.2y

-1.4 + 10.2y = 19

Solving

-1.4 + 10.2y = 19

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '1.4' to each side of the equation.

-1.4 + 1.4 + 10.2y = 19 + 1.4

Combine like terms: -1.4 + 1.4 = 0.0

0.0 + 10.2y = 19 + 1.4

10.2y = 19 + 1.4

Combine like terms: 19 + 1.4 = 20.4

10.2y = 20.4

Divide each side by '10.2'.

y = 2

Simplifying

y = 2

Answer 2

Here,

10y–0.2(7–y)=19

10y–2/10(7–y)=19

10y-1/5(7–y)=19

50y-(7-y)=95

50y-7+y=95

51y=102

y=102/51

y=2
