Answer 1

$a)x \div 5 = 1 \\ x = 1 \times 5 \\ x = 5$

$b)x \div ( - 7) = 2 \\ x= 2 \times ( - 7) \\x = - 14$

$c)x \div ( - 1) = 4 \\ x = 4 \times ( - 1) \\ x = - 4$

$d)x \div 19 = 0 \\ x = 0 \times 19 \\ x = 0$

$e)x \div 23 = - 1 \\ x = - 1 \times 23 \\ x = - 23$

$f)8 \div x = 2 \\ 8 = 2x \\ 2x = 8 \\ x = 8 \div 2 \\ x = 4$

$g)1 \div x = - 1 \\ 1= - 1x \\ -1 x = 1 \\ x = 1 \div (- 1) \\ x = - 1$

$h)2(x - 1) = 6 \\ 2x - 2 = 6 \\ 2x = 6 + 2 \\ 2x = 8 \\ x = 8 \div 2 \\ x = 4$
