Cupcake123456:
are u asking me or what ?
dude:
When you say sum I think of \(\sum\) But not sure if you've done this
Cupcake123456:
8.7 2.8x + 8.7 ?
dude:
(–2.1x + 3.7) + (5 + 4.9x) You combine like terms \(2.8x +8.7\)

11.5
dude:
No no, thats your answer, they cannot be combined \(2.8x+8.7\)
Cupcake123456:
i dont understand !
dude:
\((–2.1x + 3.7) + (5 + 4.9x)\) Okay so we can only add the numbers that have an x \(\color{red}{-2.1x+4.9x}\) and \(\color{blue}{3.7+5}\) = \(\color{red}{4.8x}+\color{blue}{8.7}\) These cannot be combined because they dont have an x
