Question

solve each of the following equations and a verify the answer in each case.​

Answer 1

Step-by-step explanation:

Solution :

$(1) \: \: \: 1 - 8z = - 7$

$\: \: \: \: \: \: - 8z = - 7 - 1$

$\: \: \: \: \: \: \: \: \: - 8z = - 8$

$\: \: \: \: \: \: \: \: \: \: \: \: 8z = 8$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: z = \frac{8}{8}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: z = 1.$

$(2) \: \: \: p + ( -1 ) = 5$

$\: \: \: \: \: \: \: p - 1 = 5$

$\: \: \: \: \: \: \: \: \: \: p = 5 + 1$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: p = 6.$
