$15 \cdot 0.7 = 0.1 y + 0.1 (15 - y)$

Step 1

Rewrite the equation as $0.1 y + 0.1 (15 - y) = 15 \cdot 0.7$ .

$0.1 y + 0.1 (15 - y) = 15 \cdot 0.7$

Step 2

Simplify $0.1 y + 0.1 (15 - y)$ .

Step 2.1.1

Apply the distributive property.

$0.1 y + 0.1 \cdot 15 + 0.1 (- y) = 15 \cdot 0.7$

Step 2.1.2

Multiply $0.1$ by $15$ .

$0.1 y + 1.5 + 0.1 (- y) = 15 \cdot 0.7$

Step 2.1.3

Multiply $- 1$ by $0.1$ .

$0.1 y + 1.5 - 0.1 y = 15 \cdot 0.7$

$0.1 y + 1.5 - 0.1 y = 15 \cdot 0.7$

Step 2.2

Simplify by adding terms.

Step 2.2.1

Subtract $0.1 y$ from $0.1 y$ .

$0 y + 1.5 = 15 \cdot 0.7$

Step 2.2.2.1

Multiply $0$ by $y$ .

$0 + 1.5 = 15 \cdot 0.7$

Step 2.2.2.2

Add $0$ and $1.5$ .

$1.5 = 15 \cdot 0.7$

$1.5 = 15 \cdot 0.7$

$1.5 = 15 \cdot 0.7$

$1.5 = 15 \cdot 0.7$

Step 3

Multiply $15$ by $0.7$ .

$1.5 = 10.5$

Step 4

Since $1.5 \neq 10.5$ , there are no solutions.
