Question

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

Answer 1

x= 5

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
