Set 15: Linear Equations

Choice A is correct. Choice Ahoice D is the correct answer. 1. Subtract 4: $\frac{2}{7}x = 2$ 2. Multiply by 7: $2x = 14$ 3. Divide by 2: $x = 7$ 4. Verify: $\frac{2}{7}(7) + 4 = 2 + 4 = 6$ ✓ Choice Ahoice C is incorrect because it results from an error in the solution process. Choice Ahoice C is incorrect because it results from an error in the solution process. Choice Ahoice D is incorrect because it results from an error in the solution process.
