一、解方程。
3X=83 X÷72=167125 ÷X=310
4X=30% 53X = 7225X-0.25=41
X×53=20×41 50% X + 54 X = 3.6 25% X + 15%X = 54
X - 15%X = 68 X- 27X =43X+83X=121
X+87X=4321X + 61X = 4 X+41X=20
6X+5 =13.4 4 X-6=38 43X+41=83
__________________________________________________
__________________________________________________ 4 X-3 ×9 = 29 5X-3×215=75 4X-6×32=2
0.36×5- 34 X= 35 X - 0.8 X= 16+6 23 ( X - 4.5) = 7
32X÷41=12 2(X-2.6)=8 25 X-13 X=310
X×( 16 + 38 )=1312 X-0.375 X =6520X–8.5= 1.5
X - 45 X -4= 21 4+0.7X=102 12 X - 25% X = 10
