[tex]{\boxed{\mathcal{\red{7\:y\:+\:21}}}}[/tex] ✔
Also,
The value of [tex]\sf\purple{"y"\:is\:-3.}[/tex] ✅
Step-by-step explanation:-
[tex]7(y + 4) - 7 = 0 \\ ➪ \: 7 \: y + 28 - 7 = 0 \\ ➪ \: 7 \: y + 21 = 0 \\ ➪ \: 7 \: y = - 21 \\ ➪ \: y = \frac{ - 21}{7} \\ ➪ \: y = - 3[/tex]
To verify:-
[tex]7 \: ( \: y + 4 \: ) - 7 = 0 \\ ⇢ \: 7 \: ( - 3 + 4) - 7 = 0 \\ ⇢ \: 7 \: (1) - 7 = 0 \\ ⇢ \: 7 - 7 = 0 \\ ⇢ \: \: 0 = 0[/tex]
[tex]\longrightarrow{\purple{L.H.S\:=R.H.S}}[/tex]
Hence Verified.
