Answer:
[tex] \frac{3 \times 4}{5 \times 4} x - \frac{3 \times 5}{4 \times 5} x = - \frac{2 \times 4}{5 \times 4} - \frac{1 \times 4}{5 \times 4} [/tex]
[tex] \frac{12x - 15x}{20} = \frac{ - 8 - 4}{20} [/tex]
/·20
12x-15x = -8-4
-3x= -12. /·(-1)
3x=12
x=4
Step-by-step explanation:
[tex] \frac{3}{5} x - \frac{3}{4} x = - \frac{2}{5} - \frac{1}{4} [/tex]
