Question

0.8y+0.25= -0.4

Solve for y

Answer 1

y = -13/16

Explanation:

Given:

0.8y+0.25= -0.4

To Find:

Solve for y

Solve:

Multiply both sides by 100

0.8y ×100 + 0.25 × 100 = -0.4×100

Simplify

80y+25 = -40

- 25 -25

----------------------

80y = -65

------ ------

80 80

y = -13/16

Answer 2

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
