Answer» Given 2 numbers X and Y,
To Find,
Solution, Triple of X added to Double of Y is equals to 144. Quarter of X is substracted from Half of Y is equals to 4. 3X + 2Y = 144 •••(1) Y/2 - X/4 = 4 •••(2) Finding the Value of Y in Form of X; Y/2 - X/4 = 4 •••(2) → Y/2 - X/4 = 4 → Y/2 = 4 + X/4 → Y/2 = (16 + X)/4 → Y = (16 + X)/4 × 2 → Y = (16 + X)/2 •••(3RD) Substituting The Value of Y in 1ST Equation; 3X + 2Y = 144 •••(1) → 3X + 2Y = 144 → 3(X) + 2(16 + X)/2 = 144 → 3X + 16 + X = 144 → 4X + 16 = 144 → 4X = 144 - 16 → 4X = 128 → X = 128/4 → X = 32 Substituting The Value of X in 3rd Equation; Y = (16 + X)/2 •••(3rd) → Y = (16 + X)/2 → Y = (16 + 32)/2 → Y = 48/2 → Y = 24 Required Answer, X = 32 Y = 24 |
