Answer:
1. 12
2. 10
3. 18
4. 6
Step-by-step explanation:
In Mathematics, substitution is a method used for solving algebraic equation by inputing the values of a given variable.
1) 4x - 4, when x = 5
4(4) - 4 =
16 - 4 = 12
2) 7 + m -2, when m = 5
7 + 5 - 2 =
12 - 2 = 10
3) 5+5h + 3, when h = 2
5 + 5(2) + 3 =
5 + 10 + 3 = 18
4) 3n - 6, when n = 4
3(4) - 6 =
12 - 6 = 6
