Solving One-Variable Linear Equations
6th Grade•40 minutes•CCSS CCSS.MATH.CONTENT.7.EE.B.4
Learning Objective
I can solve one-variable linear equations using inverse operations. 我可以使用逆运算解一元一次方程。
Key Concepts
To solve an equation, you must rearrange it so the unknown value is by itself on one side of the equal sign.
An equation is like a balance scale, so any operation performed on one side must also be performed on the other side to keep the equation balanced.
To isolate an unknown value, use the inverse operation; for example, use subtraction to undo addition.
