Y = 20
X = 70
We know Y is 20 because both triangles are the same size. 20 is in the opposite corner to Y. The right corner is 90 degrees. There are 180 degrees in a triangle. To get your answer you are going to add 20 and 90 to get 110 then you will subtract 110 from 180.
Elisa made a greater number because when you divide $140 by $20 you get 7. So that is seven Twenty dollar bills. For Ana, you divide $270 by $45 and you get 6. So for Ana you get 6 withdrawals of $45.

Move all terms that don't contain K to the right side and solve.
K= Z/3 + 3
Hello,
if the solution is infinite : the line x-3y=4 ,
so there is one line and not 2
==>x-3y=4 multiplied by 2
2x-6y=8=Q
Q=8
