Question

0,4-6=0,6x-9 Решите уравнения
3x + 16 = 9 -10x
0,6 (x + 1 23) = -1,2
-3,4 ( x+ 9 311) = -68
x3 + x4= -21
2m3 - 4m5 = 3
4a9 - 1 = 5a12

Answer 1

3x+16=9-10x<br />3x+10x=9-16<br />13x=-7<br />x=-7:13<br />x=-7/13 0.6(x+12/3)=-1.2 0.6(x+4)=-1.2 0.6x+2.4=1.2 0.6x=-3.6 x=3.6:0.6 x=6 Ответ: x=6
