Unit 2, Lesson 23

Solving Equations Using Algebra (Continued)

EngageNY 45 min(s)

Students use algebra to solve equations using techniques of making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse) to solve for the variable. Students identify and compare the sequence of operations used to find the solution to an equation algebraically, with the sequence of operations used to solve the equation with tape diagrams. Students solve equations for the value of the variable using inverse operations by making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse). As in Lesson 22, students continue solving equations using properties of equality and inverse operations to relate their steps to the steps taken when solving problems algebraically.
