Question

Tìm x

15+4.(x-2)=95

20-(x+14)=5

Answer 1

1. 15 + 4.(x-2) = 95

4.(x-2) = 95-15

4.(x-2) = 80

x - 2 = 80 : 4

x- 2 = 20

x=18

2. 20 - (x+14)=5

x+14=20-5

x+14=15

x =15-14

x= 1

Answer 2

- 15+4(x-2)=95

      4(x-2)=95-15

      4(x-2)=80

         x-2 =80:4

         x-2 =20

        x     =20+2

       x      =22

- 20-(x+14)=5

       (x+14)=20-5

        x+14=15

        x      =15-14

       x       =1

Answer 3

\(4.\left(x-2\right)=95-15\)

\(4.\left(x-2\right)=80\)

\(x-2=80:4\)

\(x-2=20\)

\(x=20+2\)

\(x=22\)

\(x+14=20-5\)

\(x+14=15\)

\(x=15-14\)

\(x=1\)

Answer 4

a, 15+4.(x-2)=95

=> 4.(x-2) = 95-15

=> 4.(x-2) = 80

=> x-2 = 80:4

=> x-2 = 20

=> x = 20+2 

+> x = 22. vậy x = 22

b, 20-(x+14) = 5 

=> x+14 = 20-5

=> x+14 =15

=> x = 15-14

=> x = 1 . Vậy x=1

Answer 5

20 - (x + 14) = 5

=> x + 14 = 15

=> x = 1

vậy_

15 + 4.(x - 2) = 95

=> 4(x - 2) = 80

=> x - 2 = 20

=> x = 22

vậy_
