The value of x and y which satisfies the equation :
9x+-5y=-34

x=1
y=8.6

Explanation:

first start by assigning a random value to a random variable, let’s say x=1

from there the equation becomes solveable

9x1+-5y=-34
simplify
9-5y=-34
-9 from both sides
-5y=-43
divide both sides by-5
y=8.6

hope this helps :)
