Solving Multistep/Variables on both sides Equations

Front

What is a multistep equation?

Back

A multistep equation is an equation that requires more than one step to solve, often involving combining like terms, using the distributive property, and isolating the variable.

Front

What does it mean to have variables on both sides of an equation?

Back

Having variables on both sides of an equation means that the variable appears on both the left and right sides, requiring manipulation to isolate the variable.

How do you solve the equation 3(s+2)-s=38?

Back

First, distribute: 3s + 6 - s = 38. Combine like terms: 2s + 6 = 38. Subtract 6 from both sides: 2s = 32. Divide by 2: s = 16.
