Решите уравнение: 1) (4,5 х+3,6) * (-16,6) = 0

2) (1,2 х+16,8) * (-13,1) = 0

3) - 32,7 * (0,1 х+6,3) = 0

4) - 15 1/13 * (1,9 х+5,7) = 0

1) (4.5x+3.6) * (-16.6) = 0

-74.7x-59.76=0

-74.7x=59.76

x=59.76: (-74.7)

x=-0.8

2) (1.2x+16.8) * (-13.1) = 0

-15.72x-220.08=0

-15.72x=220.08

x=220.08: (-15.72)

x=-14

3) - 32.7 * (0.1x=6.3) = 0

0.1x+6.3=0

0.1x=-6.3

x=-6.3:0.1

x=-63

4) - 15 1/3 * (1.9x+5.7) = 0

1.9x+5.7=0

1.9x=-5.7

x=-5.7:1.9

x=-3
