Question

-5y + 8 = -7
please help what is y?

Answer 1

`\tt \large \blue\leadsto \: \: - 5y \: + \: 8 \: = \: - 7`

`\tt \large \blue\leadsto \: \: - 5y \: = \: - 7 - 8`

`\tt \large \blue\leadsto \: \: - 5y \: = \: - 15`

`\tt \large \blue\leadsto \: \:y \: = \: \frac{ \cancel - \cancel{15}}{ \cancel- \cancel5} \\`

`\tt \large \blue\leadsto \: \:y \: = \: 3`

Answer 2

`- 5y + 8 = - 7`

`- 5y = - 7 - 8`

`- 5y = - 15`

`y = \cancel ( - 15)/( - 5) \: {}^(3)`

`y = 3`
