➷ You have to find a value that, when added to -4, gives -1
This value is +3
The factored form would be (x - 4)(x + 3)
Expand this out:
x^2 + 3x - 4x - 12
==> x^2 -x -12 = 0
w = -12

12-w=0
w=12

(b - 4z)/7 = a
b - 4z = 7a
b = 7a + 4z
Answer: b = 7a + 4z
ax - b = c
add b to both sides
ax - b + b = c + b
simplifying
ax = c + b
divide both sides by a
ax / a = (c + b) / a
simplifying
x = (c + b) / a
