Step 1.2.1

Multiply $15$ by $2$ .

$30 = 3$

$x = 15$

$x \cdot 3 = 11$

$x \cdot 4 = 16$

$x \cdot 5 = 15$

$30 = 3$

$x = 15$

$x \cdot 3 = 11$

$x \cdot 4 = 16$

$x \cdot 5 = 15$

Step 1.3

Replace all occurrences of $x$ in $x \cdot 3 = 11$ with $15$ .

$(15) \cdot 3 = 11$

$30 = 3$

$x = 15$

$x \cdot 4 = 16$

$x \cdot 5 = 15$

Step 1.4.1

Multiply $15$ by $3$ .

$45 = 11$

$30 = 3$

$x = 15$

$x \cdot 4 = 16$

$x \cdot 5 = 15$

$45 = 11$

$30 = 3$

$x = 15$

$x \cdot 4 = 16$

$x \cdot 5 = 15$

Step 1.5

Replace all occurrences of $x$ in $x \cdot 4 = 16$ with $15$ .

$(15) \cdot 4 = 16$

$45 = 11$

$30 = 3$

$x = 15$

$x \cdot 5 = 15$

Step 1.6

Step 1.6.1

Multiply $15$ by $4$ .

$60 = 16$

$45 = 11$

$30 = 3$

$x = 15$

$x \cdot 5 = 15$

$60 = 16$

$45 = 11$

$30 = 3$

$x = 15$

$x \cdot 5 = 15$

Step 1.7

Replace all occurrences of $x$ in $x \cdot 5 = 15$ with $15$ .

$(15) \cdot 5 = 15$

$60 = 16$

$45 = 11$

$30 = 3$

$x = 15$

Step 1.8

Simplify the left side.

Step 1.8.1

Multiply $15$ by $5$ .

$75 = 15$

$60 = 16$

$45 = 11$

$30 = 3$

$x = 15$

$75 = 15$

$60 = 16$

$45 = 11$

$30 = 3$

$x = 15$

$75 = 15$

$60 = 16$

$45 = 11$

$30 = 3$

$x = 15$

Step 2

Since $75 = 15$ is not true, there is no solution.

No solution
