1/2 x -2/5 x = -2

Answer 1

Hi,

Equation:

$\frac{1}{2} x - \frac{2}{5} x = - 2$

Solving:

$\frac{1}{2}x - \frac{2}{5} x = - 2 \: \: \: | \times 10 \\ 10 \times \frac{1}{2} x - 10 \times \frac{2}{5} x = - 10 \times 2 \\ 5x - 2 \times 2x = - 20 \\ 5x - 4x = - 20 \\ x = - 20 \: \: \: \: \: \: result$


Hope this helps.
