Answer:
3e = k
2a - 6 = k
k = 18
we can plug in k first for each equation
3e = 18
e = 6
2a - 6 = 18
a = 12
k = 18
e = 6
a = 12

Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from
.
-1 and 5 multiply to -5 and add to 4.

The zeros are the factors set equal to 0 and solved.
(x+5) = 0
x=-5
(x-1) = 0
x=1
