Answer 1

Answer:

Step-by-step explanation:

Answer 2

$5(x - 1) + 2(x + 3) + 6 = 0 \\ 5x - 5 + 2x + 6 + 6 = 0 \\ 7x + 7 = 0 \\ 7x = - 7 \\ x = - 1 \\ proof \\ 5( - 1 - 1) + 2( - 1 + 3) + 6 \\ = 5 \times (- 2) + 2 \times 2 + 6 \\ = - 10 + 4 + 6 \\ - 10 + 10 \\ = 0 \\ since \: lhs = rhs \: hence \: proved$
