Question 183398
<font face="Times New Roman" size="+2">

*[tex \LARGE \text{(1)          }\math  13x-3y=-50] 
*[tex \LARGE \text{(2)          }\math  12x+5y=\ \,16]


Multiply (1) by 5 and (2) by 3:


*[tex \LARGE \text{(3)          }\math  65x-15y=-250] 
*[tex \LARGE \text{(4)          }\math  36x+15y=\ \ \,48]


Add the two equations:


*[tex \LARGE \text{(5)          }\math  101x-0y=-202]


Solve for <i>x</i>, then substitute the value found for <i>x</i> into either (1) or (2) to solve for <i>y</i>.
