Question

Can I have some help? But needs to be shown with work!

Answer 1

Answer:

9) y=(-6-3x)/2                 10) y=(2x+15)/3            11) y=8+4x

12) y=1/2x+6                   13) y= (8-3x)/-4            14) y= (10-6x)/-2

Step-by-step explanation:

The methods I used are known as float and ping, and escalator:

9) We can float the 3x to the other side to make

2y=-6-3x

We now escalate the 2 down to make:

y= $\frac{-6-3x}{2}$

10) We simply escalate the 3 down to give:

y= $\frac{2x+15}{3}$

11) We simply float the -4x to the other side:

y=8+4x

12) For this question, it will be better to expand the bracket first:

y-8=-1/2x-2

Now we float the -8 to the other side to give:

y=-1/2x-2+8

Which can be simplified to give:

y=1/2x+6

13) We simply float the 3x to the other side to give:

-4y=8-3x

Now we escalate the -4 down to give:

y= $\frac{(8-3x)}{-4}$  
14) We float the 6x to the other side to give:

-2y=10-6x

Now we escalate the -2 down to give:

y= $\frac{10-6x}{-2}$
