Answer:
The value of the second expression is 8, so the expressions are not equivalent.
Explanation:
Given expressions:
x + x + 6 and 4 + 3 x - 2
When x = 4
Put x = 4 in both expression;
Expression 1 :
x + x + 6 = 4 +4 + 6 = 14
Expression 2 :
4 + 3x - 2 = 4 + 3(4) - 2 = 14
When x = 2
Put x = 2 in both expression ;
Expression 1 :
x + x + 6 = 2 + 2 + 6 = 10
Expression 2:
4 + 3x - 2 = 4 + 3(2) - 2 = 8
