Question

Subtract 3x – 4y – 7z from the sum of x – 3y + 2z and -4x + 9y – 11z​

Answer 1

according to the question,

• x - 3y + 2z + (-4x + 9y - 11z)
• -3x + 6y -9z

now,

• -3x + 6y -9z - (3x - 4y -7z)
• -3x + 6y -9z -3x + 4y + 7z
• -6x + 10y - 2z

is the required answer .

Answer 2

Answer:

$\huge\mathfrak\purple{Answer}$

= x - 3y + 2z + (-4x) + 9y - 11z - (3x - 4y - 7z)

= x - 3y + 2z - 4x + 9y - 11z - 3x + 4y + 7z

= x - 4x - 3x + 2z - 11z + 7z + 9y + 4y

= -3x - 3x + 2z - 4z + 13y

= -6x - 2z + 13y
