Answer:
y=11
x=8
Step-by-step explanation:
This is Elimination
2x+2y=38
Subtract 2x on both sides 2y=-2x+38
Then Multiply 2(y=x+3) which equals 2y=2x+6
Solve by Elimination
2y=-2x+38
2y=2x+6
add the y's and since the x's are different those cancel out, then add 38 and 6.
then you do the equation 4y=44
divide both by 4
y=11
then you do 11=x+3
subtract 3 on both sides
x=8
and there you go
I hope this is how you wanted it solved

Step-by-step explanation:
River valley provided fertile land and access to water.
Not:
dense forests: hard to navigate, not suitable for ancient civilizations
mountain passes: same reason as above
smooth coastlnes: settlements potentially could be washed away or destroyed. Access to fresh, non-salt water, also was harder than that of settling in river valleys
