Answer 1

Answer:

I didn't understand the question may be later sorry

Answer 2

Step-by-step explanation:

$\mathtt{ \implies \:a = 6 - b }$

$\mathtt \red{ \implies \: 6 - b - b = 8}$

$\mathtt \blue{ \implies \: 6 - 2b = 8}$

$\mathtt \pink{ \implies \:6 + 8 = 2b }$

$\mathtt \purple{ \implies \: 2b = 14}$

$\mathtt{ \implies \: b = 7}$

$\mathtt{ \implies \: a = 6 - 7 \quad \quad (\therefore \: b = 7)}$

$\mathtt{ \implies \:a = - 1 }$

$\mathtt{ \implies \:so \: a \times b = - 1 \times 7 }$

$\mathtt{ \implies \: ab = - 7}$
