Answer:

y = 2x + 3

Step-by-step explanation:

Hello!

Solve for y by isolating the variable.

Solve for y

  • [tex]-20x + 10y = 30[/tex]
  • [tex]10y = 30 + 20x[/tex]
  • [tex]y = \frac{30 + 20x}{10}[/tex]
  • [tex]y = \frac{(10)(3 + 2x)}{10}[/tex]
  • [tex]y = 3 + 2x[/tex]
  • [tex]y = 2x + 3[/tex]

The solution is y = 2x + 3.

To Calculate :-

  • Value of y.

Solution :-

⇒ -20x + 10y = 30

☆ Transposing (-20x) to R.H.S. sign would be changed to positive.

⇒ 10y = 30 + 20x

⇒ y = 30 + 20x / 10

⇒ y = 10 (3 + 2x) / 10

☆ Cancelling 10,

⇒ y = 3 + 2x / 1

⇒ y = 2x + 3
