Answer:
10 is NOT a solution for -2 (x - 13) - 7 + 5 x <0
Step-by-step explanation:
Here, the given expression is : -2 (x - 13) - 7 + 5 x <0
To check : If it holds true for x = 10
Put x = 10 in the lefts side, we get:
-2 (x - 13) - 7 + 5 x = -2 ( 10 -13) - 7 + 5 (10)
= -2 (-3) -7 + 50
= 6 - 7 + 50 = -1 + 50
= 49
⇒ at x = 10 , -2 (x - 13) - 7 + 5 x = 49
and Right side of the inequality is 0.
49 < 0 is a contradiction , as 49 ≮ ( is not less than) 0
Hence, 10 is NOT a solution for -2 (x - 13) - 7 + 5 x <0
