一、解方程。
3X= X÷= ÷X=
=30% X = X-0.25=
X×=20× 50% X + X = 3.6 25% X + 15%X =
X - 15%X = 68 X- X = X+X=121
X+X= X + X = 4 X+X=20
6X+5 =13.4 4 X-6=38 X+=
4 X-3 ×9 = 29 5X-3×= 4X-6×=2
0.36×5- X= X - 0.8 X= 16+6 ( X - 4.5) = 7
X÷=12 2(X-2.6)=8 X-X=
X×( + )= X-0.375 X = 20 X– 8.5= 1.5
X - X -4= 21 4+0.7X=102 X - 25% X = 10
