Answer:
2y=8-x
y-2x=-1
y-2x=-1
y = 2x-1
Substitute for y in the 1st
2(2x-1)=8-x
4x-2=8-x
5x = 10
x = 2
y=2x-1
y = 3
Explanation:
2y=8-x
y-2x=-1
------------
Rearrange:
x = 8-2y
y = 2x-1
------------
Substitute to get:
y = 2(8-2y)-1
y = 16-4y-1
5y = 15
y = 3
-------------------
Substitute to solve for "x":
x = 8-2(3)
x = 2

Answer:
PS = RT, PQ = ST Give?
PQ+QS=PS Segment Addition
ST+QS=RT False - should be ST + QS = PS by Substitution
RS+ST=RT Segment Addition
ST+QS=RS+ST Equal of equals are equal
QS=RS Subtraction Property of Equality
Because of the error in 3 the proof is incorrect, i.e. QS ≠ RS
