How do I solve this equation? <br> 4-y/5=2-2y/8
Aliun [14]

y=−40

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4−y5=2−2y8

4+−15y=2+−14y

−15y+4=−14y+2

Step 2: Add 1/4y to both sides.

−15y+4+14y=−14y+2+14y

120y+4=2

Step 3: Subtract 4 from both sides.

120y+4−4=2−4

120y=−2

Step 4: Multiply both sides by 20.

20*(120y)=(20)*(−2)

Answer:

y=−40

tester [92]
<h3>Answer: b) 5 & 1/2</h3>

Work Shown:

Add the fractional portions

3/10 + 2/10 = (3+2)/10 = 5/10 = 1/2

To go from 5/10 to 1/2, you divide both parts by 5

The whole parts of the mixed numbers given add to 2+3 = 5

The whole parts add to 5, the fractional parts add to 1/2, giving us 5 & 1/2
