Question

From the sum of 3x + 2y - 9 and 2x - 6y + 2 subtract the sum of 4x - 9y - 1 and -3x+8y+7​

Answer 1

Step-by-step explanation:

3x + 2y - 9 + 2x - 6y + 2

= 5x - 4y - 7

4x - 9y - 1 - 3x + 8y + 7

= x - y + 6

= 5x - 4y - 7 - x - y + 6

= 4x - 5y - 1

So the answer is : 4x - 5y - 1

Answer 2

✯Solution✯

• Sum of 3x + 2y - 9 and 2x - 6y + 2 :-

➔ 3x + 2y - 9 and 2x - 6y + 2

➔ 3x + 2y - 9 + 2x - 6y + 2

➔ 5x - 4y - 7

• Sum of 4x - 9y - 1 and -3x + 8y + 7 :-

➔ 4x - 9y - 1 and 3x + 8y + 7

➔ 4x - 9y -1 - 3x + 8y + 7

➔ x - y + 6

• Subtract 5x - 4y - 7 and 7x - y + 6 :-

➔ ( 5x - 4y - 7 ) - ( x - y + 6 )

➔ 5x - 4y - 7 -x - y + 6

➔ 4x - 5y - 1

➛ Final answer is 4x - 5y - 1
