Solution:

Note that:

  • Given equation: 4(k + 1) = k + 10
  • To find: 3k

Simplifying the LHS:

  • 4(k + 1) = k + 10
  • => (4 x k) + (4 x 1) = k + 10
  • => 4k + 4 = k + 10

Subtracting k and 4 both sides:

  • 4k + 4 - k - 4 = k + 10 - k - 4
  • => 3k = 6 (No further solution required)

The value of 3k is 6.
