Question

convert it into equation and solve it

a. 12+ x = 56

b. x-55=123

c. x - 45 = 56

d. 2x =18​

Answer 1

Step-by-step explanation:

(a) 12+X =56 ;X=56-12=44

(b) x-55 =123;X= 123+55=178

(c)x-45 = 56 ;x =56+45 = 101

(d)2x =18 ; X = 18/2 =9

Answer 2

(a) 12+x

or, x + 12 –12 = 56 – 12

or, x+0=44

or, x=44

(b) x – 55

or, x – 55 = 123+55

or, x = 178

(c) x-45=56

or, ,x–45+45=56+45

or, x–0=101

or, x =101

(d)
