Tell whether the given value is a solution of the inequality.
n–3≤4;n=7
Given inequality: n–3≤4andn=7
We will check solution by putting value:
Put
n=7 in n–3≤4
⇒7–3≤4
∴4≤4, This is true.
Hence, Yes the given value is a solution of the inequality.
Check whether the value given in the brackets is a solution to the given equation or not:
(a) n + 5 = 19 (n = 1) (b) 7n + 5 = 19 (n = − 2)
(c) 7n + 5 = 19 (n = 2) (d) 4p − 3 = 13 (p = 1)
(e) 4p − 3 = 13 (p = − 4) (f) 4p − 3 = 13 (p = 0)
