Answer 1

t = 7.2. m = -59

Объяснение:

Answer 2

$\frac{t+4}{7} = \frac{3t-4}{11}$

$\frac{t+4}{4} - \frac{3t-4}{11}$ = 0

$\frac{11(t+4)}{4*11} - \frac{4(3t-4)}{4*11} =0$

$\frac{11t+44}{44} - \frac{12t-16}{44} = 0$

$\frac{-t+28}{44} = 0$

x = 7.2

$\frac{m}{15} - \frac{3m-1}{30} =2$

$\frac{m}{15} - \frac{3m-1}{30} - 2 = 0$

$\frac{2m}{15*2} - \frac{3m-1}{30} - 2*30 = 0$

$2m-3m+1-60=0$

-m - 59 = 0

-m = 59

m = -59
