1) write a pair of simultaneous equations in x and y to represent the given info above

Is the ans = 1x+2y=$8.00

3X+1y=$9.00

How do i find the cost of one biscuit and one cup of ice cream??

**drwls**, Sunday, June 14, 2009 at 8:40amThose are the correct equations, but you do not have to write the "1" as a coefficient. In algebra, that just isn't done.

Just solve these two equations:

x + 2y = 8

3x = y = 9

You can rewrite the first equation as

3x + 6y = 24

By subtracting the 2nd eq from the 3rd), you eliminate x and get

5y = 15

Take it from there.
