Card 1Solving linear inequations in natural numbers

Solve: 13x < 200 when x is a natural number.

Answer

Step 1: Divide both sides by 13. 13x < 200 x < 200/13 x < 15 5/13 Step 2: Choose natural numbers less than 15 5/13. Answer: {15, 14, 13, 12, 11, 10, ..., 3, 2, 1}…

Card 2Solving linear inequations in integers

Solve: 13x < 200 when x is an integer.

Answer

Step 1: Divide both sides by 13. 13x < 200 x < 200/13 x < 15 5/13 Step 2: Choose integers less than 15 5/13. Answer: {..., -3, -2, -1, 0, 1, 2, 3, 4, 5, ..., 15}…

Card 3Solving linear inequations with natural number replacement set

Solve: 3 - 2x ≥ x - 12 for x ∈ N.

Answer

Step 1: Bring variable terms to one side and numbers to the other. 3 - 2x ≥ x - 12 3 + 12 ≥ x + 2x 15 ≥ 3x Step 2: Divide by 3. 5 ≥ x Step 3: Write natural number values. Answer: {1, 2, 3, 4, 5}…

Card 4Solving linear inequations with whole number replacement set

Solve: 7 + 3x ≤ 35 - 2x for whole numbers.

Answer

Step 1: Collect x terms on one side. 7 + 3x ≤ 35 - 2x 3x + 2x ≤ 35 - 7 5x ≤ 28 Step 2: Divide by 5. x ≤ 5 3/5 Step 3: Choose whole numbers. Answer: {0, 1, 2, 3, 4, 5}…

Card 5Solving linear inequations with integer replacement set

Solve: 2x - 3/2 ≥ 6 - 5x for integers.

Answer

Step 1: Add 5x to both sides. 2x - 3/2 + 5x ≥ 6 7x - 3/2 ≥ 6 Step 2: Add 3/2 to both sides. 7x ≥ 6 + 3/2 7x ≥ 15/2 Step 3: Divide by 7. x ≥ 15/14 x ≥ 1 1/14 Step 4: Choose integers. Answer: {2, 3, 4, …

Card 6Solving linear inequations in real numbers

Solve: 3x + 1 ≥ 10 for real numbers.

Answer

Step 1: Subtract 1 from both sides. 3x ≥ 9 Step 2: Divide by 3. x ≥ 3 Answer: x ≥ 3…

Card 7Solving inequations with brackets

Solve: 2(2x + 3) - 10 < 6(x - 2).

Answer

Step 1: Expand both sides. 4x + 6 - 10 < 6x - 12 4x - 4 < 6x - 12 Step 2: Bring x terms together. -4 + 12 < 6x - 4x 8 < 2x Step 3: Divide by 2. 4 < x Answer: x > 4…

Card 8Solving inequations with fractions

Solve: (x - 2)/3 ≥ 2.

Answer

Step 1: Multiply both sides by 3. x - 2 ≥ 6 Step 2: Add 2 to both sides. x ≥ 8 Answer: x ≥ 8…
