Solving for "x"

First, we combine similar terms. Put to the left those with variable (With x), and to the right those constants.

*Remember to change "signs" when you move.

Given: 10x + 9 = 5x +29

Perform operations indicated:

Divide both terms by "5" to isolate x:

x=4, Answer

To check, substitute x to the given eqn:


, good


Next, 10x -13 = 7x +2
Combine similar terms:

Perform operations indicated (Add, Substract, etc):

Divide 3 both terms to isolate x:

x=5

Check by substituting to the given eqn:


, good

Thank you,
