Question

Решите неравенства, срочно!!!!!!
2-3y > -4
5(x-1)+7≤1-3(x+2)
25x² + 64>0
25x²+64<0

Answer 1

1) 2-3y>-4                     2) 5(x-1)+7≤1-3(x+2)
   -3y>-4-2                         5x-5+7≤1-3x-6 
   -3y>-6 |: (-3)                   5x+3x≤1-6+5-7 
   y<2                               8x≤-7  
                                        x= -7:8
