The word algebra originate from baghdad.
Answer:
23
Step-by-step explanation:
Simplify the following:
(-66)/(-3) - 4 - -5
The gcd of -66 and -3 is -3, so (-66)/(-3) = (-3×22)/(-3×1) = (-3)/(-3)×22 = 22:
22 - 4 - -5
-(-5) = 5:
22 - 4 + 5
22 + 5 = 27:
27 - 4
| 2 | 7
- | | 4
| 2 | 3:
Answer: 23
4x+15y=13 (1)
3x+5y=16 (2)
(2) * 3 --> 9x+15y=48 becomes (3)
(3) - (1)
5x=35
x=7
sub x =7 into (1)
4(7)+15y=13
28+15y=13
-28 -28
15y= -15
y= -15/15
y= -1
therefore x=7 and y= -1
x^3+8x+5-2x^2+3x+12
x^3-2x^2+11x+17 (is your simplified answer)
