Review for one and two step equation flashcard

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step by performing the same operation on both sides to isolate the variable.

Front

What is a two-step equation?

Back

A two-step equation is an equation that requires two operations to isolate the variable, typically involving addition or subtraction followed by multiplication or division.

Front

Solve for a: 19 + a = -50

Back

a = -69

Front

Solve for y: 3y = 9

Back

y = 3

Front

What is the first step to solve the equation 3c + 5 = 23?

Back

Subtract 5 from both sides to isolate the term with the variable.

Front

Solve for c: 3c + 5 = 23

Back

c = 6

Front
