5y +9y = 3/4-6/2+8
3/4= 0.75 and 6/2 =3
so
14y=5.75
then Y = 5,75 ÷ 14 = 0.4107

Hey there!
Here's the answer.
5y-3/4+9y+6/2=8 --> Write the problem.
5y+9y-3/4+6/2=8 --> Gather the y terms together and the constant terms together.
14y+9/4=8 --> Simplify the above equation.
14y=23/4 --> Subtract 9/4 on both sides of the equation.
y=23/56 Divide 14 on both sides of the equation.
So the answer is y=23/56.
Hope it helps!

5y-3/4 + 9y+6/2 =8
add the y terms: 14y - 3/4 + 6/2 = 8
convert 6/2 and 8 to fourths to make the addition easy: 14y -3/4 +12/2 = 32/4
Do the subtraction: 14y + 9/4 = 32/4
Subtract 9/4 from both sides: 14y = 23/4
Divide both sides by 14: y = 23/56

Solve the following systems of equations for x and y 1). y = 3 + 3x y = 18 - 2x 3x - y = -3 2x + y = 18 5x = 15 x = 3 y = 12 2). 18x + 6y = 120 4x + 3y = 40 8x + 6y = 80 10x = 40 x = 4 y = 8

I am assuming that this is
(5y-3)/4 +(9y+6)/2 =8. If so, start by multiplying by your greatest common denominator to get rid of all fractions, (in this case 4). So, you are left with:
5y-3 + 18y +12=32.
Now combine like terms to get: 23y+9=32
Subtract 9 from both sides: 23y=23
Divide both sides by 23 and y=1

5y -3/4 + 9y +6/2 =8
(5y + 9y) - 3/4 + 6/2 =8
14y = 8 + 3/4 - 6/2
y = 5.75/14
y = 0.41

5y-3/4+9y+6/2=8
Combine like terms:
5y+9y=3/4-3+8
14y=3/4+5
Multiply through by 4:
4(14y)=4(3/4+5)
56y=3+20
56y=23
Divide both sides by 56:
y=23/56

original problem
1. 5y- 3/4 + 9y+6/2 =8
combine like terms
2. 14y- 3/4+6/2=8
subtract 6/2 from both sides
3. 14y- 3/4+ 6/2 = 8
+14y- 3/4 - 6/2 = 8 - 6/2
---------------------------
14y- 3/4 = 5
add 3/4 to both sides
4. 14y - 3/4 = 5
+14y+ 3/4 = 5+ 3/4
-----------------------------
14y = 5+ 3/4
multiply 4 in all sides to eliminate the fraction
5. 14y (4) = 5 (4)- 3/4(4)
6. 56y = 20+ 3
56y = 23
you can divide each side by 56 to get y by itself.
56y = 23
----- -----
56 56
y= 23/56 or 0.41

5Y-3/4+9Y+6/2=8
To make it easier get all whole numbers.
5y-0.75+9Y+3=8
Collect like terms
14y+2.25=8
Isolate the term.
14y=5.75
Isolate the variable.
y=0.41
