How to solve equations in the first volume of fifth grade mathematics

0.3 x = 7.2 x+450 = 550 0.6+x = 2.7 x-0.52 = 1.3 13.2+x = 16.3

x÷ 14 = 98 x-35 = 95 76+x = 9 1x+4.8 = 8 x-4.5 = 3.6

0.8+x = 9. 1 4x = 168 x÷3 = 5.5 0.9x = 2.43 x÷ 1.2 = 7

x-257 = 582 x÷ 15 = 180 14x = 7 x÷2.5 = 0.8 360+x = 7 10

1.5 x = 4.5 120-x = 35 3.6÷x = 0.6 5x = 40 x+4. 1 = 9

x- 105 = 15 x÷0.7 = 1.2 2. 1x = 0.84 x = 56 = 102 2 2.4÷x = 6

x-970 = 270 20x = 160 6.6+x = 24.5 15x = 3 12.6-x = 3.6
