2x - 4(x-4) = -2 + 3x + 3
2x - 4x + 16 = 3x + 1
-2x + 16 = 3x + 1
5x = 15
x = 3

LN = 120 and a = 10
<u>Step-by-step explanation:</u>
If we need to find the variable a as, LN is the line and M is the mid point between L and N. So LN = LM + MN
LM = 4a = 40
a =
= 10
MN = 8a = 8×10 = 80
So LN = LM + MN
LN = 40 + 80 = 120
