The second question (x-2.6) on page 7 1 in the fifth grade of mathematics = 8.5 (x =1.5) =17.58 (x-6.2) = 41.6 (x-3) divided by 2.
2(x-2.6)= 8 5(x+ 1.5)= 17.5

Solution: 2(x-2.6)÷2=8÷2 Solution: 5 (x+1.5) ÷ 5 =17.5 ÷ 0.5.

x-2.6 =4 x+ 1.5=3.5

x-2.6+2.6 = 4+2.6 x+ 1.5- 1.5 = 3.5- 1.5

x=6.6 x=2

8(x-6.2)=4 1.6 ( x-3)÷2=7.5

Solution: 8 (x-6.2) ÷ 8 = 4 1.6 ÷ 8 solution: (x-3)÷2×2=7.5×2.

x-6.2=5.2 x-3= 15

x-6.2+6.2 = 5.2+6.2 x-3+3 = 15+3

x= 1 1.4 x= 18
