Answer:

y = -13/16

Explanation:

Given:

0.8y+0.25= -0.4

To Find:

Solve for y

Solution:

Multiply both sides by 100


0.8y\cdot \:100+0.25\cdot \:100=-0.4\cdot \:100

Simplify


80y+25=-40

Subtract 25 from both sides


80y+25-25=-40-25

Simplify


80y=-65

Divide both sides by 80


(80y)/(80)=(-65)/(80)

Simplify


y=-(13)/(16)

Thus, y = -13/16

or in decimal form it equal y = -0.8125
