Step-by-step explanation:

Given Find the sum of the following expressions

a) 6d-4c,-7c + 6d

b) -4pq + 2hk qp + 5kh

Expand and simplify each of the following expressions

a) a+7+3(a-2)

b) 6(x+2y) -4y

  • We need to find te sum of the given expressions
  • So  6d – 4c – 7c + 6d
  •    = 12 d – 11 c
  • Since all the three does not have same or like terms it is not able to add the given numbers and has to be kept as it is.
  • So  it will be – 4pq + 2hkqp + 5kh
  • We need to expand and simplify
  • So a + 7 + 3(a – 2)
  • Or a + 7 + 3a – 6
  • Or  it will be 4a + 1
  • So 6 (x + 2y) – 4y
  • = 6x + 12y – 4y
  • = 6x + 8y
  • = 2(3x + 4y)

Find the sum of the following expressions

a) 6d-4c,-7c + 6d

= 6d - 4c + (-7c) + 6d

= 6d - 4c - 7c + 6d

= 12d - 11c

b) -4pq + 2hk, qp + 5kh

= -4pq + 2hk + qp + 5kh

= -3pq + 7kh

Expand and simplify each of the following expressions

a) a+7+3(a-2)

= a + 7 + 3a - 6

= 4a + 1

b) 6(x+2y) -4y

= 6x + 12y - 4y

= 6x + 8y
