Equivalent Expressions

Equivalent Expressions are expressions that look different but work the same. I find an equivalent expression for the following, 15 - 3(2x + 4) 3(2a-4) + 3a You can find an equivalent expression by appling the distributive property and then combining like terms. Math Standards Covered CCSS.MATH.CONTENT.6.EE.A.3 Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y State of Georgia Standard MGSE6.EE.4 Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions 𝑦 + 𝑦 + 𝑦 and 3𝑦 are equivalent because they name the same number regardless of which number 𝑦 stands for.
