The Answer Is <span>factor by grouping</span>
<span> x = 3y - 8
</span>
Plug this in for variable x in equation [2]<span>
</span><span><span> [2] 3•(3y-8) + 2y = 31
</span><span> [2] 11y = 55
</span></span>
Solve equation [2] for the variable y
<span><span> [2] 11y = 55</span>
<span> [2] y = 5</span> </span>
// By now we know this much :
<span><span> x = 3y-8</span>
<span> y = 5</span></span>
<span>// Use the y value to solve for x
</span>
<span> x = 3(5)-8 = 7 </span>Solution :<span><span> {x,y} = {7,5}</span>
