A= - 12

W =-4×7

W= - 28

Answer 2

ANSWER:

(i) 5x - 6 = 9

➝ x = 3

____________

(ii)$\frac{a}{4}\:-3 = 8$

➝ $a\:=\:44$

-------------------------

SOLUTION:

(i) 5x - 6 = 9

➝ 5x = 9 + 6

➝ x = 15 ÷ 5

➝ x = 3

Let's check our answer

5 × 3 -6 = 9

15 - 6 = 9

9 = 9

LHS = RHS

Hence, checked

____________

(ii)$\frac{a}{4}\:-3 = 8$

➝ $\frac{a}{4}\: = \:8\:+\:3$

➝ $a\:=11\:×\:4$

➝ $a\:=\:44$

Let's check !

$\frac{44}{4}\:-3 = 8$

11 - 3 = 8

8 = 8

LHS = RHS

Hence, checked
