Solve using linear combination. Show all work. 9X + 5Y 35 And -2x-5y=0
2 answers:
Answer:
x=5, y=-2
Step-by-step explanation:
9x + 5y =35
-2x-5y=0
Add the equations together
9x + 5y =35
-2x-5y=0
----------------------
7x = 35
Divide each side by 7
7x/7 = 35/7
x = 5
Now find y
9x+5y = 35
9(5) +5y = 35
45 +5y =35
Subtract 45 from each side
45-45 +5y = 35-45
5y = -10
Divide each side by 5
5y/5=-10/5
y = -2
Answer:
solve your equation then Subtract 2x from both sides next Subtract 2 from both sides. last Divide both sides by 2

Answer:
1) as-16a
taknig a as common
=a(s-16)
2)as-4a³
taking a as common
=a(s-4a²)
3)2a³+8a-4a²-16
taking common terms
=2a(a²+4)-4(a²+4)
=(2a-4)(a²+4)
again taking common
=2(a-2)(a²+4)
