Question

pls answer fast it is very important​

Answer 1

Answer:

Its as below described.

Step-by-step explanation:

(1) 2*x + 7 = 11

2*x = 11-7 = 4

X = 4/2

= 2

(2) 2*x - 3 = 7

2*x = 7+3=10

x = 10/2

X = 5

(3) 2*x/3 = 2

2*x = 3*2 = 6

X = 6/2

X = 3

(4) x/4 = 9

X = 9*4

X = 36

Answer 2

Answer:

a ) 2x + 7 = 11

    2x = 11 -7

    2x =4

    x= 4/2 = 2

  the answer given in the bracket is correct.

b) 2x - 3 = 7

   2x = 7+3

   2x = 10

    x = 10/2 = 5

   The answer given in bracket i.e. (2) is not correct.

c) 2x /3 = 2

  2x = 6

   x= 3

  The answer given in bracket is correct.

d) x/4 =9

  x = 36

  The answer given in bracket i.e. (20) is not correct.
