Question

In the equation y = 2(x + 5), if x is increased by 3, then y is increased by

6

3

5

11

Answer 1

`x = (y)/(2)- 5`

`x = (1)/(2) y - 5`

Explanation:

`1. \: (y)/(2) = x + 5 \\ 2. \: (y)/(2) - 5 = x \\ 3. \: x = (y)/(2) - 5 \\ \\ or \\ \\ 1. \: 2x + 10 = y \\ 2. \: 2x = y - 10 \\ 3. \: (2x)/(2) = (y - 10)/(2) \\ x = (1)/(2) y - 5`
