1 answer:
Answer:
X - Y = 11 -------1
2x + y = 19 --------2
<em><u>Solving</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>elimination</u></em><em><u> </u></em><em><u>method</u></em><em><u> </u></em>
Multiple equation 1 by 2
2( X - y )= 22
2x - 2y = 22
2x + y = 19
Y = 3
Putting value of y= 3 in equation 1
X - 3 = 11
X = 11 + 3
X = 14
<h3>Value of X = 14 and Y = 3 </h3>
