Answer 2

Answer:

Hey there! For (vii) (x-3,7) = (5,7) Thus, x-3 = 5 x = 8. For (viii) (2,2y-3) = (2,7) Thus 2y-3 = 7 2y = 10 y = 5. Hence: X = 8. Y = 5. acobdarfq

Step-by-step explanation:

The given inequality is, 5x−3<7

⇒5x−3+3<7+3

⇒5x<10

⇒

5

5x

<

5

10

⇒x<2

(i) The integers less than 2 are .......,−4,−3,−3,−1,0,1.

Thus when x is an integer, the solutions of the given inequality are

all the integral values of x which are less than 2.

(ii) When x is real number the solution is given by x<2,

i.e., all real numbers x which are less than 2.

Thus, the solution set of the given inequality is x∈(−∞,2)
