70%X+ 20%X = 3.6 X×3/5=20×1/4 25%+ 10X = 4/5
X- 15%X = 68 X+3/8X=121 5X-3×5/21=5/7
2/3X÷1/4=12 6X+5 =13.4 6X+5 =13.4 4χ-6=38
x- 0.8x = 16+6 20 x–8.5= 1.5
X+25%X=90 4x-3 ×9 = 29 X-0.125X=8
x-0.8x = 16+6 20 x– 8.5= 1.5 x-4/5x -4= 21
4x-3 ×9 = 29 4χ-6=38 X+25%X=90
X-0.125X=8 5 X-2.4×5=8 x- 0.8x = 16+6
X- 15%X = 68 X+3/8X=121 5X-3×5/21=5/7
