Find RS. Explain your reasoning.

6x + 5=9x - 4

x = 3

Step-by-step explanation:

Given the equation :

6x + 5=9x - 4

Collect like terms :

6x - 9x = - 4 - 5

-3x = - 9

Divide both sides by - 3

-3x / - 3 = - 9 / - 3

x = 3

Hence, x = 3

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
