x/2 = x/5

Solution

\frac{x}{2} = \frac{x}{5}

x = 0

Solution steps

\frac{x}{2} = \frac{x}{5}

Apply fraction cross multiply: if

\frac{a}{b} = \frac{c}{d}

then

a \cdot d = b \cdot c

x \cdot 5 = 2 x

Move

2 x

to the left side

3 x = 0

Divide both sides by

3

x = 0

2 x - 3 < 13

x^{2} + 6 x - 40 \geq 0

2 \cdot (7 x - 1) - 8 x < 3 \cdot (2 x - 1)

\frac{n}{- 5} = 7

x^{2} - 7 x + 12 \leq 0
