Quick Question
How t.f do you not know how to do this yo own damn self?!
Answer:
t = 0
Step-by-step explanation:
8t + 72 = 72
-72 -72
8t = 0
/8 /8
t = 0
I think it's B.8 but I don't know for sure.
Given the equation <span>-4a/a+4=12/a-11, for sure we need to the solution for a.
</span><span>-4a/a+4=12/a-11
</span>-3a + 4 = 12/a - 11
-3a -12/a = -11 - 4
3a + 12 / a = 15
(3a^2 + 12) / a = 15
3a^2 + 12 = 15a
<span>3a^2 - 15a + 12 = 0
</span>
In order to get a , we need to find the roots.
(3a - 3) (a - 4) = 0
3a - 3 = 0 --> a = 1
a - 4 = 0 -- > a = 4
So the possible solutions for a are 1 and 4.
Answer:
x=-2
Step-by-step explanation:
-2x-7=3(4x+7)
distribute
-2x-7 = 3*4x +3*7
-2x-7 = 12x+21
add 2x to each side
-2x-7+2x = 12x+2x+21
-7 = 14x+21
subtract 21 from each side
-7-21 = 14x+21-21
-28 = 14x
divide by 14
-28/14 = 14x/14
-2 =x
