#### Understanding

This lesson allows students to deepen their understanding of solution strategies for equations in one variable.

### What to look for

Students may be challenged when looking for solution pathways that are non-routine.

### Sample Assessment

Which equation has the same solution as \(4-2(x-5)=x-19\)?a. \(2(x+5)=-8\)

b. \(3(x-3 )=9\)

c. \(x+2=2x-3\)

d. \(3x-4= 2x+7\)

Answer: d. \(3x-4=2x+7\)
