5x-2y=3
-5x+4y=9
2y= 12
divide it by 2
y= 6
put y in any equation
5x-2 (6)=3
5x-12=3
5x= 3+12=15
divide by 5
x=3
y= 6

Answer:
yes she will have enough, they will have 17 dollars left
Step-by-step explanation:
84 times 5 is 420 so she will have enough
Its a squared + xb squared = c squared so its 11 squared + 11 squared equals c squared. So I'm gonna take it down to the next step and say 11x11+ 11x11= c squared, then you end up with 121+121= c squared then you add those two and end up with 242= c squared, so then you find the square root of 242 so you should end up with 15.5 and the number goes on and on and on
