To simplify the expression \( 5a + 3b - 3a + 4b + 7c \), we can combine like terms.
Combine the \( a \) terms: \[ 5a - 3a = 2a \]
Combine the \( b \) terms: \[ 3b + 4b = 7b \]
The \( c \) term remains as is: \[ 7c \]
Putting it all together, the simplified expression is: \[ 2a + 7b + 7c \]
Let's go through the simplification step-by-step again.
Starting with the expression:
\[ 5a + 3b - 3a + 4b + 7c \]
Combine the \( a \) terms: \[ 5a - 3a = 2a \]
Combine the \( b \) terms: \[ 3b + 4b = 7b \]
The \( c \) term remains unchanged: \[ 7c \]
Now, putting it all together gives us:
\[ 2a + 7b + 7c \]
It appears the previous response was indeed correct. The simplified expression is \( 2a + 7b + 7c \). If there is a specific aspect of the problem or expression that you would like to clarify or if there was a misunderstanding, please let me know!
To simplify the expression \( 4.5x - 2 + 3.7x + 6.5 \), we will combine like terms.
Combine the \( x \) terms: \[ 4.5x + 3.7x = (4.5 + 3.7)x = 8.2x \]
Combine the constant terms: \[ -2 + 6.5 = 4.5 \]
Now, putting it all together gives us:
\[ 8.2x + 4.5 \]
So, the simplified expression is:
\[ \boxed{8.2x + 4.5} \]
