You must join like terms in algebraic formulas in order to add two of them.
(4x - 1) + (-6x + 3)
The coefficients of the similar terms must first be added.
4x + (-6x) = -2x
and
-1 + 3 = 2
The abbreviated form is thus:
-2x + 2
As a result, (4x - 1) + (-6x + 3) equals -2x + 2.
Please be aware that the terms can be added in any order. The outcome will be the same in the end.
