a x 4 = e
b / 4 = e
c + 4 = 3
d - 4 = e
a + b + c + d = 100
a x 4 = e
a = e/4
b / 4 = e
b = 4e
c + 4 = e
c = e - 4
d - 4 = e
d = e + 4
e/4 + 4e + e - 4 + e + 4 = 100
e/4 + 4e + 2e = 100
e/4 + 6e = 100
e(1/4 + 6) = 100
e (1/4 + 6*4/4) = 100
e (1/4 + 24/4) = 100
e (25/4) = 100
e = 100 ÷ 25/4
e = 100 x 4/25
e = 400 / 25
e = 16
a = e/4 ⇒ 16/4 ⇒ a = 4
b = 4e ⇒ 4*16 ⇒ b = 64
c = e - 4 ⇒ 16 - 4 ⇒ c = 12
d = e + 4 ⇒ 16 + 4 ⇒ d = 20
a + b + c + d = 100
4 + 64 + 12 + 20 = 100
100 = 100
