Answer:
The first thing you would solve is 10^2.
Step-by-step explanation:
This is because in the order of operations, parenthesis comes first - which you don't have any of - and then exponents come second.
Number 1 is 4 4/5#2 is-3 #3 is > anf # 4 is 13 units
y= 2x-10
y=4x-8
------------subtract
0 = -2x - 2
-2x=2
x = -1
y= 2x-10
y= 2(-1)-10
y = -2 - 10
y = -12
answer: x = -1 and y = -12 or (-1,-12)
