Question

Simplify combining like terms:
21b - 32 + 7b - 205 ​

Answer 1

$\huge{\mathfrak\red{Combining \: like \: terms}}$

$\huge 21b-32+7b-205$

$\huge (21b+7b)-(205-32)$

$\huge{\mathfrak{We \: know \: that \: -, - = +}} </p><p>$

$\huge{\purple{(21+7b)-205+32}}$

$\huge{\blue{28b-237}}$

$\huge{\pink\therefore \: {209b}}$
