解方程 1112X-120%X=6.5 | 4X+0.4X=70.4 |
3X+90%×4=9 | 1112X-120%=6.5. |
(1)1112X-120%X=6.5,
1110.8x=6.5,
1110.8x÷1110.8=6.5÷1110.8,
x=
65
11108;
(2)4X+0.4X=70.4,
4.4x=70.4,
4.4x÷4.4=70.4÷4.4,
x=16;
(3)3X+90%×4=9,
3x+3.6-3.6=9-3.6,
3x÷3=5.4÷3,
x=1.8;
(4)1112X-120%X=6.5,
1110.8x=6.5,
1110.8x÷1110.8=6.5÷1110.8,
x=
65
11108.
1110.8x=6.5,
1110.8x÷1110.8=6.5÷1110.8,
x=
65
11108;
(2)4X+0.4X=70.4,
4.4x=70.4,
4.4x÷4.4=70.4÷4.4,
x=16;
(3)3X+90%×4=9,
3x+3.6-3.6=9-3.6,
3x÷3=5.4÷3,
x=1.8;
(4)1112X-120%X=6.5,
1110.8x=6.5,
1110.8x÷1110.8=6.5÷1110.8,
x=
65
11108.
