Below are sample questions representative of the exercises included on this worksheet and related 7.90 Strategic choice of methods and justification skill assessments:

Problem 1Difficulty: Mastery

Classify the system: 3x + 4y = 2 and 6x + 8y = 5. Which strategy is most efficient, and why?

ANotice the second equation’s left side is 2 times the first; compare constants to see the system has no solution.

BSolve by substitution because there are two variables.

CGraph because you must see the intersection point.

DAdd the equations because adding always eliminates a variable.

Solution & Explanation:Doubling 3x + 4y = 2 gives 6x + 8y = 4, but the second equation says 6x + 8y = 5. Same left side, different right side → no solution. Checking proportional equations is fastest.

Problem 2Difficulty: Mastery

The equation 12 - 3(4 - x) = 3x is given. Which strategy is most efficient to determine the solution set, and why?

ASubtract 12 first because constants must be removed first.

BDivide both sides by 3 because 3 is common.

CMove 3x to the left first because variables must be together.

DDistribute -3 and simplify because it may turn into an identity where both sides match.

Solution & Explanation:Distribute: 12 - 3(4 - x) = 12 - (12 - 3x) = 12 - 12 + 3x = 3x. The equation becomes 3x = 3x, true for all x → infinitely many solutions.

Problem 3Difficulty: Mastery

Solve (x - 5)(x + 2) = 0. Which strategy is most efficient, and why?

AExpand to get x squared - 3x - 10 = 0 because you must always expand.

BTake the square root of both sides because it is a product.

CUse the zero product property because a product equals 0 only if at least one factor equals 0.

DDivide both sides by x because x is in the expression.

Solution & Explanation:Set each factor to 0: x - 5 = 0 gives x = 5, and x + 2 = 0 gives x = -2. Zero product is the direct method when the equation is already factored.
