Answer:
Simplified expression is 5x + 9 and coefficient are 5 & 9.
Explanation:
Given Expression: 3x + 2 - 3x + 7 + 5x
we need to simply the given expression and find the coefficient in the simplified expression.
First we group the like term,
we get
3x - 3x + 5x + 2 + 7
Now solve like term,
= ( 3x - 3x + 5x ) + ( 2 + 7 )
= 5x + 9
Constant Coefficient of x = 5
and Coefficient of 9 = 9
therefore, Simplified expression is 5x + 9 and coefficient are 5 & 9.
