Answer:
-3x - 5
Explanation:
Combining like terms is the process of adding the coefficients of the same term (such as a variable).
For example:
4x + 3x = (4 + 3)x = 7x, since the coefficients 4 and 3 are both multiplied by the same term (x)
Applying this to the problem at hand:
-7x - 2 + 4x - 3
↓ regrouping using the commutative property of addition/subtraction
= -7x + 4x - 2 - 3
↓ combining like terms
= (-7 + 4)x - 5
= -3x - 5
