Question

решите уравнение:

4(0,385х - 1,54) - 8,35 + 1,68х = 11,25

Answer 1

1,54х-6,16-8,35+1,68=11,25

1,54х+1,68х=11,25+6,16+8,35

3,22х=25,76

х=8

Answer 2

4(0,385x-1,54)-8,35+1,68x=11,25

1.54x-6.16-8.35+1.68x-11.25=0

1.54x-14.51+1.68x-11.25=0

3.22x-14.51-11.25=0

3.22x-25.76=0

x=25.76/3.22

x=8
