Solve 2(x + 3) = x - 4

x = -10

Step-by-step explanation:

first, expand the left side of the equation (distributive property):

2x + 6 = x - 4

then, subtract x and 6 on both sides to put like terms together:

2x - x = -4 - 6

combine like terms:

x = -10

done! hope this helps!

   2(x + 3) = x - 4

=> 2x + 6 = x - 4

=> 2x -x = -4 -6

=> x = - 10

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
