Please help me! How do u do these?

Answer:
Q3: x = -2
Q6: x = -24
Step-by-step explanation:
Q3:
[tex]3 - x = 5[/tex]
A rule in algebra that you must follow is that whatever you do to the left, you do to the right.
For this question, subtract 3 from both sides to isolate the variable x.
[tex] - x = 5 - 3[/tex]
[tex] - x = 2[/tex]
Now, divide both sides by -1.
[tex] \frac{ - x}{ - 1} = \frac{2}{ - 1} [/tex]
[tex]x = - 2[/tex]
Q6:
[tex] \frac{x}{6} = - 4[/tex]
Multiply both sides by 6:
[tex]x = - 4 \times 6[/tex]
[tex]x = - 24[/tex]
