First bring all the terms with variable on one side and the take numbers to the other side.
5y+9y=10-4
14y=6
y=6/14
y=3/7...

The answer is y = 3/7
5y + 4 = 10 - 9y
14y + 4 = 10
14y = 6
y = 6/14
y = 3/7
*** However *** , are you sure that the question isn't "5Y minus 4"? That would seem more likely since that would give you a neat answer of y = 1
e.g.
5y - 4 = 10 - 9y
14y - 4 = 10
14y = 14
y = 1

5y + 4 = 10 - 9y
5y + 9y =10 - 4
14y = 6
y = 6 / 14
y = 3 / 7

5y+4=10-9y
add 9y to both sides
14y + 4 = 10
subtract 4 from both sides
14y = 6
y = 6/14 = 3/7
.

you combine like elements in the equation:
5y + 4 = 10 - 9y
Subtract 5y from both sides of the equation:
4 = 10 - 9y - 5y
4 = 10 - 14y
Subtract 10 from both sides of the equation:
4 - 10 = -14y
-6 = -14y
Divide -14 on both sides of the equation:
-6/-14 = y
3/7 = y

get like terms on the same side so you can solve for y.
5y + 9y = 10-4
14y = 6
y = 6/14
y = 3/7 or 0.42857

5y+4=10-9y
9y+5y+4=10-9y+9y
14y+4=10
14y+4-4=10-4
14y=6
y=6/14=3/7

you have to transpose ^^
. 5y +( 4 - 4) = 10 - 9y -4
. 5y + 9y = 10 - (9y + 9y) - 4
. 14y = 10 - 4
. 14y = 6
. 14y/14 = 6/14
. y = 6/14 or 3/7 or 0.42857143 (or 0.43)
