– 1.2m 0.2 = 3.8 + m (x + 12)2 = 9 3-135. Are there solutions to the equations in the previous problem that are not allowed? Methods for Solving One-Variable Equations Here are three different methods you can use to solve one-variable equations: Rewriting: Use algebraic techniques to rewrite the 5(x – 1) equation. This will = 15 often involve using 5x – 5 = the Distributive 15 Property to get rid 5x = 20 of x = 4 parentheses. Then solve the equation using solution methods you know. Looking 5(x – 1) inside: Choose a = 15 part of the 5( 3 ) equation that = 15 – includes the x 1 = variable and is 3 grouped together x = 4
