Evaluate 3+11t -9u3+11t−9u3, plus, 11, t, minus, 9, u when t=9t=9t, equals, 9 and u=11u=11u, equals, 11. Hint #11 / 4
Let's substitute \pink t=\pink 9t=9start color #ff00af, t, end color #ff00af, equals, start color #ff00af, 9, end color #ff00af and \blue u=\blue{11}u=11start color #6495ed, u, end color #6495ed, equals, start color #6495ed, 11, end color #6495ed into the expression.
Hint #22 / 4
\phantom{=}3+11\pink {t} -9{\blue{u}}=3+11t−9uempty space, 3, plus, 11, start color #ff00af, t, end color #ff00af, minus, 9, start color #6495ed, u, end color #6495ed
=3+11(\pink {9}) -9{(\blue{11})}=3+11(9)−9(11)equals , 3, plus, 11, left parenthesis, start color #ff00af, 9, end color #ff00af, right parenthesis, minus, 9, left parenthesis, start color #6495ed, 11, end color #6495ed, right parenthesis
Hint #33 / 4
=3+99-99=3+99−99equals, 3, plus, 99, minus, 99
Hint #44 / 4
=3=3equals, 3
