Question

Simplify 1 - 2u + u + 4

Answer 1

Step-by-step explanation:

1 - 2u + u + 4 = 0

5 - 3u = 0

3u = 5

u = 5upon 3

Answer 2

$1−2++4$

${\color{#c92786}{1}}-2u+u+{\color{#c92786}{4}}1−2u+u+4$

$5−2+$

$5−2+$

$5{\color{#c92786}{-2u}}+{\color{#c92786}{u}}5−2u+u$

$5−$

$5−$

${\color{#c92786}{5-u}}5−u$

$−u+5$
