You and a friend of getting ready to study for an assessment on expressions and
equations. Knowing that your friend is still getting expressions and equations mixed
up and doesn’t always know how to tell if two expressions or two equations are
equivalent, your job is to create a set of problems (and solutions) to help your friend
study. Create a minimum of six problems that will address your friend’s misconcep-
tions and include the solutions for her/him to study. Make sure your reasoning is
clearly articulated in the solutions.
Here are six problems and their solutions to help you study expressions and equations.
Explanation:Here are six problems to help you study expressions and equations:
Simplify the expression (3x - 4) + (2x + 5).Solution: Combine like terms: 3x + 2x - 4 + 5 = 5x + 1.Solve the equation 2x + 3 = 9.Solution: Subtract 3 from both sides: 2x = 6. Divide both sides by 2: x = 3.Determine if the expressions 2x + 5 and 5 + 2x are equivalent.Solution: Since addition is commutative, the expressions are equivalent.Determine if the equations 2x + 3 = 9 and 2x + 6 = 12 are equivalent.Solution: Subtracting 3 from both sides of the first equation gives 2x = 6, which is equivalent to the second equation.Simplify the expression 2(3x + 4) - (5x - 2).Solution: Distribute the 2: 6x + 8 - (5x - 2). Use the distributive property: 6x + 8 - 5x + 2. Combine like terms: x + 10.Solve the equation 3(x - 2) = 9.Solution: Distribute the 3: 3x - 6 = 9. Add 6 to both sides: 3x = 15. Divide both sides by 3: x = 5.Learn more about Expressions and Equations here:https://brainly.com/question/11537309
