Question 29603: The total of two numbers is 16. The first number plus 2 more than 3 times the second equals 18. I'm not sure on this one but I gave it a shot
4x + 12y = 16
If you add the first number which is 4 plus 2 more = 4+2 = 6 x 3 = 18

You can put this solution on YOUR website!
you have 2 equations here .... the first number is m the second is n
m + n = 16
m + 3n + 2 = 18
solve the first equation for m
+m+%2B+n+=+16+
+m+=+16+-+n+ plug this into the second equation
+m+%2B+3n+%2B+2+=+18+
+16+-+n+%2B+3n+%2B+2+=+18+ combine like terms
+18+%2B+2n++=+18+ subtract 18 from both sides
+2n+=+0+
+n+=+0+ plug this the first equation.
+m+%2B+n+=+16+
+m+%2B+0+=+16+
+m+=+16+ plug both answers into the 2nd equation
+m+%2B+3n+%2B+2+=+18+
+16+%2B+3%280%29+%2B+2+=+18+ combine terms
+16+%2B+0+%2B+2+=+18+
+18+=+18+ YES!
