w=0.8358

See steps

Step-by-step explanation

1. Simplify the expression

$0.15 w \cdot 0.35 = 0.22 w - 0.14$

Group like terms:

$(0.15 \cdot 0.35) w = 0.22 w - 0.14$

Multiply the coefficients:

$0.0525 w = 0.22 w - 0.14$

2. Group all w terms on the left side of the equation

$0.0525 w = 0.22 w - 0.14$

Subtract $0.22 w$ from both sides:

$(0.0525 w) - 0.22 w = (0.22 w - 0.14) - 0.22 w$

Simplify the arithmetic:

$- 0.1675 w = (0.22 w - 0.14) - 0.22 w$

Group like terms:

$- 0.1675 w = (0.22 w - 0.22 w) - 0.14$

Simplify the arithmetic:

$- 0.1675 w = - 0.14$

3. Isolate the w

$- 0.1675 w = - 0.14$

Divide both sides by -0.1675:

$\frac{(- 0.1675 w)}{- 0.1675} = \frac{- 0.14}{- 0.1675}$

Cancel out the negatives:

$\frac{0.1675 w}{0.1675} = \frac{- 0.14}{- 0.1675}$

Simplify the arithmetic:

$w = \frac{- 0.14}{- 0.1675}$

Cancel out the negatives:

$w = \frac{0.14}{0.1675}$

Simplify the arithmetic:

$w = 0.8358$

Why learn this

Linear equations cannot tell you the future, but they can give you a good idea of what to expect so you can plan ahead. How long will it take you to fill your swimming pool? How much money will you earn during summer break? What are the quantities you need for your favorite recipe to make enough for all your friends?

Linear equations explain some of the relationships between what we know and what we want to know and can help us solve a wide range of problems we might encounter in our everyday lives.
