Question

3x-4(64-x) is equal to 10. find x and check your answer.. ​

Answer 1

3x - 4×(64-x) = 10

3x - 256 + 4x = 10

7x - 256 = 10

7x = 10 + 256

7x = 266

x = 266/7

x= 38

verification

3×38 -4(64-38)

= 10

hence verified

hope it helps :)

Answer 2

3x -4(64-x) =10

=>3x-256+ 4x =10

7x -256 =10

7x =10+256

7x =266

x =266/7

x =38

check this

3×38 -4(64- 38) =10

114 -4×26 =10

114 -104 =10

10 =10
