0.8y+0.25= -0.4 Solve for y

disa [49]

Answer:

y = -13/16

Step-by-step 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

$\frac{80y}{80}=\frac{-65}{80}$

Simplify

$y=-\frac{13}{16}$

Thus, y = -13/16

or in decimal form it equal y = -0.8125
