Answer:
(c) 2x -4y +3z
Step-by-step explanation:
The given expression 4x − 5y + 2z + y − 2x + z is simplified by combining like terms.
Like terms are combined by adding their coefficients.
4x − 5y + 2z + y − 2x + z
= (4 -2)x +(-5 +1)y +(2 +1)z
= 2x -4y +3z
Combining like terms, the simplified expression is given by:
2x - 4y + 3z.
An expression is simplified combining like terms, that is, adding or subtracting the terms that have the same variable.
In this problem, the expression is given by:
4x - 5y + 2z + y - 2x + z.
The like terms are given as follows:
Hence the simplified expression is given by:
2x - 4y + 3z.
