To solve for equations when more than one equation property is required, first simplify the equation and then use the addition or subtractio property for equations. Then you are ready to use the multiplication and division property for equations.
1. Combine like terms (the same variable) to simplify.
x+2x+5=x+19
3x + 5 = x + 9

2. since 3x > x, we will undo x on the right side. To do that, Subtract x both sides.
3x + 5 - x = x + 9 - x
2x + 5 = 9

3. Since there is a variable on the left side of the equation, we will undo 5. To do that, Subtract 5 both sides.
2x + 5 - 5 = 9 - 5
2x = 4

4. to solve for x, divide both sides by 2.
