solve 5y - y/2 = 4?

5y - y/2 = 4
2(5y - y/2) = 2(4)
2*5y - 2*y/2 = 2*4
10y - y = 8
9y = 8
y = 8/9

4(y-2)=5y-(y+a million) Use the distributive propety and do 4 cases y and then 4 cases -2 then -a million cases y and then -a million cases a million. 4y-eight=5y-y-a million Now Simplify (5y-y) 4y-eight=4y-a million deliver over the 4y to get Y on the two sides and you may routinely deliver the awesome area variable over to the left area. 4y - 4y - eight = -a million as quickly as you're taking 4y - 4y the two could finally end up being 0 so it may be -eight = -a million. for this reason you may deliver the -eight over to -a million and you gets 0 = 7 0 for sure does not equivalent to 7 regardless of in case you extra the -a million over it may be -7 = 0 so for this reason the answer is fake. you may resolve the equation each and each of ways regardless of in case you start to unravel it and ascertain it isnt actual, through fact in case you dont teach all your artwork the instructor will mark you down.

10y-y=8
9y=8
y=8/9
Check: 10(8/9)-8/9=72/9
80/9-8/9=72/9
72/9=72/9=8

5y-y/2=4

10y-y/2=4
9y=4*2
9y=8
y=8/9

5y-y/2=4
Multiply both side by 2
it'll be 10y-y=8
9y = 8
so, y = 8/9

10y - y = 8
9y = 8
y = 8/9

5y-y/2=4?
ans: (5-1/2)y=4
(9/2)y=4
y=8/9

so then 9y/2=4
y=8/9

5y-y/2 = (10y-y)/2=4
9y = 8 thus y = 8/9

5y-y/2 = 4
10y-y = 8
9y = 8
y = (8/9)
