Answer:
4) d = 1
5) w = 11
6) q = 120
Step-by-step explanation:
4) [tex]9d - 5 = 4[/tex]
Adding 5 on both the sides ,
[tex] = > 9d - 5 + 5 = 4 + 5[/tex]
[tex] = > 9d = 9[/tex]
Dividing both the sides by 9 ,
[tex] = > \frac{9d}{9} = \frac{9}{9} [/tex]
[tex] = > d = 1[/tex]
5) [tex]6 - 3w = - 27[/tex]
Substracting 6 from both the sides ,
[tex]6 - 3w - 6 = - 27 - 6[/tex]
[tex] = > - 3w = - 33[/tex]
Dividing both the sides by -3 ,
[tex] = > \frac{ - 3w}{ - 3} = \frac{ - 33}{ - 3} [/tex]
[tex] = > w = 11[/tex]
6) [tex] - 4 = \frac{q}{8} - 19[/tex]
Adding 19 on both the sides ,
[tex] \frac{q}{8} - 19 + 19 = - 4 + 19[/tex]
[tex] = > \frac{q}{8} = 15[/tex]
Multiplying both the sides by 8 ,
[tex] = > \frac{q}{8} \times 8 = 15 \times 8[/tex]
[tex] = > q = 120[/tex]
