total value=88=totalvalueoftickets
88=2x+3y
total tickets s 40
x+y=40
we hae
88=2x+3y
40=x+y
eliminate
times second equation by -2 and add to first equation to eliminate x
88=2x+3y
-80=-2x-2y +
8=0x+1y
8=y
sub
x+y=40
x+8=40
minus 8
x=32
he sold 32 x tickets
sold 8 y tickets
88=2x+3y
total tickets s 40

For total ticket equation use the given: X+Y=40 then, for second equation on prices 2X+3Y=88
So the equations are:
X+Y=40 and 2X+3Y=88
To solve:
take first equation and place x by itself X=(40-Y) then take the equation and place them together:
2(40-Y)+3Y=88 then Foil;
(80-2Y)+3Y=88 Now combine like terms;
3Y-2Y=88-80 ---> Y=8 after place Y=8 in first equation;
X+Y=40 ---> X+8=40 ---> X=32
So the answers are: X=32 and Y=8
A little more than you asked but hope this helps :)
