Answer :
we cannot find out what x is specifially since ther is another place holder but we can solve for x but manipluation the equation
-3x-5y=-10
add 10 to both sides
10-3x-5y=0
add 3x to both sides
10-5y=3x
divide both sides by 3
(10-5y)/3=x
so if you find y you can find x
-3x-5y=-10
add 10 to both sides
10-3x-5y=0
add 3x to both sides
10-5y=3x
divide both sides by 3
(10-5y)/3=x
so if you find y you can find x
