Question

5( x + 35 ) = 515

96 - 3( x + 1 ) = 42

Answer 1

5(x+35)=515

x+35 = 515 ÷5

x+35 = 103

x = 103-35

x = 68

Answer 2

Đúng ko

Answer 3

5( x + 35) = 515

x + 35 = 515 : 5

x + 35 = 103

x = 103 - 35

x = 68

96 - 3( x +1) = 42

3( x+1) = 96 - 42

3(x +1) = 54

x +1 = 54 : 3

x + 1 = 18

x = 18-1

x =17

chắc chắn nha bn!!!

Answer 4

5( x + 35 ) = 515

x + 35 = 515 : 5

x + 35 =103

x = 103 - 35

x = 68

96 - 3( x +1 ) = 42

3( x + 1 ) = 96-42

3( x +1 ) = 54

x + 1 = 54 : 3

x + 1 = 18

x = 18 - 1

x = 17

Answer 5

a) 5(x + 35 ) = 515

x + 35 = 515:5

x + 35 = 103

x = 103 - 35

x = 68

b) 96 - 3(x + 1) = 42

3(x + 1) = 96-42

3(x + 1) = 54

x + 1 = 54 : 3

x + 1 = 18

x = 18 - 1

x = 17
