Answer 2

`\sf b = \sf ((c - 2a))/(2) \\`

Explanation:

`\sf \: 2a + 2b = c \\`

To remove 2a, subtract both sides by 2a.

`\sf \: 2a - 2a + 2b = c - 2a \\ \sf 2b = c - 2a \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:`

Divide both sides by 2.

`\sf (2b)/(2) = ((c - 2a))/(2) \\ \\ \sf b = \sf ((c - 2a))/(2)`
