How do you solve this equation7x+9=3x+29

x= 5

Step-by-step explanation:

First, subtract the smallest variable to both sides to move the variable to one side.

7x+9= 3x+29

-3x      -3x

Now, subtract 9 to both sides.

4x+9= 29

    -9   -9

Finally, divide by 4 to both sides to isolate the variable.

4x= 20

4     4

x=5

for the points! : )

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
