Hello from MrBillDoesMath!
Answer: b
Discussion:
7b + 3 - 4b = 3 - 3(b+4) =>
7b + 3 - 4b = 3 - 3b -12 =>
(7b - 4b) + 3 = -3b - 9 =>
3b + 3 = -3b -9 => Add 9 to both sides
3b + 12 = -3b -9 + 9 =>
3b + 12 = -3b => ( add 3b to both sides)
6b + 12 = 0 => (subtract 12 from both sides)
6b = -12 =>
b = -12/6 = -2
Thank you,
MrB
Answer:
x + 3 + 
Step-by-step explanation:
Using long division
x + 3 ← quotient
--------------------------
x - 3 | x² + 0x + 4
x² - 3x ↓
------------------------
3x + 4
3x - 9
-----------------------
13 ← remainder
Thus
= x + 3 +
