Question
A= 5x-3y +2z, B= 4x-2y+3z, C= 6x-4y -4z, Find A-B+C
Hint:
Put values of A, B, and C in expression A-B+C to get the answer.
The correct answer is: Hence, the value of A-B+C is 7x - 5y - 5z.
Answer:
- Step by step explanation:
○ Given:
A= 5x-3y +2z,
B= 4x-2y+3z,
C= 6x-4y -4z,
Find A-B+C
○ Step 1:
○ Put values of A, B and C in (A-B+C)
We get,
A-B+C
(5x-3y +2z) - (4x-2y+3z) + (6x-4y -4z)
○ Step 2:
○ Group like terms
(5x-4x +6x) - (3y-2y+4y) + (2z-3z -4z)
7x - 5y - 5z
- Final Answer:
Hence, the value of A-B+C is 7x - 5y - 5z.
○ Step 1:
○ Put values of A, B and C in (A-B+C)
We get,
(5x-3y +2z) - (4x-2y+3z) + (6x-4y -4z)○ Step 2:
○ Group like terms
(5x-4x +6x) - (3y-2y+4y) + (2z-3z -4z) 7x - 5y - 5zRelated Questions to study

Graph the equation 
We can find the tabular values for any points of x and then plot them on the graph. But we usually choose values for which calculating y is easier. This makes plotting the graph simpler. We can also find the values by putting different values of y in the equation to get different values for x. Either way, we need points satisfying the equation to plot its graph
