a, b and e
a.
x + 5 = 8 ( subtract 5 from both sides )
x = 3
b
4x = 12 ( divide both sides by 4 )
x = 3
c
= 3 ( multiply both sides by 9 )
x = 27
d
x - 5 = 10 ( add 5 to both sides )
x = 15
e
= 3
note that
= x, hence
x = 3

:DDDDDDD
Answer:
x=-4
Step-by-step explanation:
5x=3x-8 you subtract 3x from both sides.
2x=-8 then you divide by the number next to the x. meaning 2
x=-4
(6x^4) + (15x^3)(y^2) + (3x^2)(y^3) is your answer
As we are looking at descending powers of x. Look at the powers of the x. In the first one (6x^4), the power is 4, and 4 is greater than the other numbers given (3 & 2). Therefore, the order given above is correct.
hope this helps
