Multiple choice general knowledge math & puzzles Solve the two equaions 4x+6y=12 2x+8y=10 then values of x and y respectively 1.6 and 1.2 0.8 and 1.8 1.8 and 0.8 1.2 and 1.6 Reveal answer Fill a bubble to check yourself C Correct answer Explanation Multiplying the second equation by 2: 4x + 16y = 20. Subtracting the first (4x + 6y = 12) gives 10y = 8, so y = 0.8. Substituting y into 2x + 8(0.8) = 10 gives 2x + 6.4 = 10, 2x = 3.6, x = 1.8.
