Question 181138
<font face="Times New Roman" size="+2">


You have two different expressions in <i>x</i>, both equal to <i>y</i>.  So set them equal to one another.


*[tex \Large \text{          }\math y=2x+9]


and


*[tex \Large \text{          }\math y=7x+10]



So


*[tex \Large \text{          }\math 7x+10=2x+9]
