Question

4(k+1)=k+10,then 3k=

A. 3/2
B.5/2
C. 2
D. 6​

Answer 1

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.
