J = K+6
K + J = 4K
<span>Replace J in the second equation </span>
K + (K + 6) = 4K
K + K + 6 = 4K
2K + 6 = 4K
Subtract 2K from each side
6 = 2K
Divide both sides by 2
K=3
<span>So, Keisha is 3 and therefore John is 9 because 3 + 6=9</span>
Answer:
See below.
Step-by-step explanation:
1/(x + 1) consists of 1 factor, 1/(x + 1)
1/[a(x + 1)] consists of two factors, 1/a and 1/(x + 1)
The LCM is 1/[a(x + 1)]
The LCD is a(x + 1)
3x - 6y = -15
5x - 2x = 3x
-9y + 3y = -6y
-26 + 11 = -15
