[tex]\tt \large \blue\leadsto \: \: - 5y \: + \: 8 \: = \: - 7[/tex]

[tex]\tt \large \blue\leadsto \: \: - 5y \: = \: - 7 - 8[/tex]

[tex]\tt \large \blue\leadsto \: \: - 5y \: = \: - 15[/tex]

[tex]\tt \large \blue\leadsto \: \:y \: = \: \frac{ \cancel - \cancel{15}}{ \cancel- \cancel5} \\ [/tex]

[tex]\tt \large \blue\leadsto \: \:y \: = \: 3[/tex]

Answer:

[tex] - 5y + 8 = - 7[/tex]

[tex] - 5y = - 7 - 8[/tex]

[tex] - 5y = - 15[/tex]

[tex]y = \cancel \frac{ - 15}{ - 5} \: {}^{3} [/tex]

[tex]y = 3[/tex]
