8(x - 6) = -(x + 3) step by step

x=5

Step-by-step explanation:

Start by simplifying the parenthesis

the - in front of (x+3) is -1 so let's write that instead

Now lets start isolating x by adding 48 on both sides

Now add x on both sides to fully isolate x

Finally divide by 9 on both sides

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
