Answer 1

$\huge \blue{ \mid{ \underline{ \overline{ \tt answer : - }} \mid}}$

Answer 2

Distribute

10=4+3(+12)

10=4+{\color{#c92786}{3(t+12)}}10=4+3(t+12)

10=4+3+36

10=4+{\color{#c92786}{3t+36}}10=4+3t+36

2

Add the numbers

10=4+3+36

10={\color{#c92786}{4}}+3t+{\color{#c92786}{36}}10=4+3t+36

10=40+3

10={\color{#c92786}{40}}+3t10=40+3t

3

Rearrange terms

10=40+3

10={\color{#c92786}{40+3t}}10=40+3t

10=3+40

10={\color{#c92786}{3t+40}}10=3t+40
