Answer:
y = 7
Step-by-step explanation:
1) Substitute X with 1
9 ( 1 ) - 2y = - 5
2) Simplify 19×1 to 9
9 − 2y = −5
3) Subtract 9 from both sides
−2y = −5 − 9
4) Simplify −5−9 to −14
−2y = −14
5) Divide both sides by −2.
y = -14 / -2
6) Two negatives make a positive.
y = 14 / 2
7) Simplify 14 / 2 to 7
y = 7
1000 meters are 1km so 700 meters
