according to question

$x + 4 = 9 \\ \\ subtract \: 4 \: from \: both \: sides \\ \\ \implies \: x + 4 - 4 = 9 - 4 \\ \\ \implies \: x = 9 - 4 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \implies \: x = 5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

hence, value of x is 5
