Question

Tìm x 

10 + 2 *x =4^2

24+2 * x = 64

Answer 1

10+2*x=4^2

10+2*x=16

2*x=16-10

2*x=6

x=6:2

x=3

24+2*x=64

2*x=64-24

2*x=40

x=40:2

x=20

Answer 2

10 + 2 *x =4^2

10 + 2 *x = 16

       2 *x = 16 - 10

       2 *x = 6

           x= 6 : 2

           x = 3

24+2 * x = 64

2 * x = 64 - 24

2 * x = 40

x = 40 : 2 

x = 20
