Question

Please help me! How do u do these?

Answer 1

Answer:

Q3: x = -2

Q6: x = -24

Step-by-step explanation:

Q3:

$3 - x = 5$

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.

$- x = 5 - 3$

$- x = 2$

Now, divide both sides by -1.

$\frac{ - x}{ - 1} = \frac{2}{ - 1}$

$x = - 2$

Q6:

$\frac{x}{6} = - 4$

Multiply both sides by 6:

$x = - 4 \times 6$

$x = - 24$
