Answer:
-1/5 or - .2
Step-by-step explanation:
4x(2+8)= -8
(4*-.2)(2+8)= -8
-.8(2+8)= -8
-.8(10)= -8
-8=-8
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.
