Answer:
15
Step-by-step explanation:
x - y = 10, then x = 10 + y
x + y = 20
substitute for x:
10 + y + y = 20
2y = 10
y = 5
x = 10 + 5 = 15

Rewrite it to simplify using order of operations.
P E M D A S
() ^2 × ÷ + -
So nw it's
5-1-(9÷3)-9
no now it's
(5-1)-(3-9)
4-(-6) I wrote the negative in parentheses to show its not an additional subtraction sign. also if you look it's sort of a plus sign. so when you subtraction (-6) from 4 it's actually 4+6
4-(-6)=10.
that's what I got. hope this helps.

It wouldn’t let me type the symbol haha
