1.	A) three times a number added to another number gives 25. Take the numbers as x and y and form equationb) instead of adding if the number is subtracted we get 17 . Using this idea and form another equation .c) find the numbers ?
Answer» Step-by-step explanation: Let the numbers be X and Y 3X+Y = 25 (Equation 1) If INSTEAD of adding,the number is subtracted we get 3X - Y = 17 (Equation 2) Now ADD equation 1 and 2 we get (3X+Y)+(3X-Y) = 25+17 6X = 42 Thus X = 7 Now putting the value of X in Equation 1 we get 3X+Y = 25, 3*7 +Y = 25 Y = 25-21 = 4 Thus Y = 4 Thus our required numbers are X = 7 and Y = 4

Answer»

Step-by-step explanation:

Let the numbers be X and Y

If INSTEAD of adding,the number is subtracted we get

Now ADD equation 1 and 2 we get

Now putting the value of X in Equation 1 we get

Thus our required numbers are X = 7 and Y = 4
