Solution:
<u>Note that:</u>
- Given equation: 4(k + 1) = k + 10
- To find: 3k
<u>Simplifying the LHS:</u>
- 4(k + 1) = k + 10
- => (4 x k) + (4 x 1) = k + 10
- => 4k + 4 = k + 10
<u>Subtracting k and 4 both sides:</u>
- 4k + 4 - k - 4 = k + 10 - k - 4
- => 3k = 6 (No further solution required)
The value of 3k is 6.
