combine like terms

2x-3x+7-10+2x

1 answer

To combine like terms in the expression \(2x - 3x + 7 - 10 + 2x\), we can group the \(x\) terms and the constant terms separately.

  1. Combine the \(x\) terms: \[ 2x - 3x + 2x = (2 - 3 + 2)x = 1x = x \]

  2. Combine the constant terms: \[ 7 - 10 = -3 \]

Now, putting it all together, we have: \[ x - 3 \]

So, the combined expression is: \[ \boxed{x - 3} \]
