Question

Check whether the value given in the brackets is a solution to the given equation or not: i) 9x-14=40 (x=6) ii) 3x+18=3 (x= -5)

Answer 1

Answer:

yes the answer given in the bracket are correct

Step-by-step explanation:

9x-14=40

9x=40+14

9x=54 => x=6

(ii) 3x+18=3

3x= 3-18

3x=-15

x= -5

Answer 2

Answer:

Answer:i) 9x-14=40

Answer:i) 9x-14=40or,9.(6)-14=40 [because x=6]

or,54-14 =40

or,54-14 =40ii) 3x+18=3

or,3.(-5)+18=3

or,-15+18=3[because+sine greater than-sine]
