X-1.4+0.6=2.4
X-1.4+0.6=2.4
X-1.4+0.6=2.4
x=2.4+1.4-0.6
x=3.2
x-0.6x=2.4
X-1.4+0.6=2.4
2.4x-1.4x+3x+2.4=0
2.4x+1.4x+2.4=3x
2.4x-1.4x-3x=5.2-8
9-1.4x=9.8x-2.4
2.4x-9.8=1.4x-9,
2.4x-1.4x=5.2-8
0.6X+1.4X=8.2-5.4
4x-1.4x-3x+2.4=02.4x-1.4x-3x+2.4=0
X+0.6x=2.4怎么解
x+6x=8.4 2.4x+x=27.2 9x-4.2x=24 x-0.6x=4.8 8.6x-4.6x=10.4 7x+0.3x=3.65解方程要过程详细.
X-1.4+0.6=2.4 解方程
9x-0.9乘7=2x+2.1 x=?9x-0.9乘7=2x+2.1 x=?还有:3(2x-1.2)=2(x+3.5) x=?2.4x-9.8=1.4x-9
方程:3(2x-1.2)=2(x+3.5) 2.4x-9.8=1.4x-9
求未知数x x等于2x=12.6 0.6x+1.4=5
1.4x-x=9.8求x
x+(x-1.4)+1.5x=33.
