Answer:
C, 4+x=15
Step-by-step explanation:
since you're trying to find x you need to isolate it, so use the other numbers you have, 19 and 4, subtract 4 from 19, (19-4) to get x=15.
The answer is C because 4 + 15 = 19.

8463/32=264 15/32
Step-by-step explanation:
Let's make every fraction improper first.
7 3/4=31/4
5 2/8=42/8
6 1/2=13/2
Simplify 42/8
42/8=21/4
21/4
31/4
13/2=26/4
21/14*31/4*26/4=(21*31*26)/64=16926/64=8463/32
A) 9(x + 4) = 27
9x + 36 = 27
9x = 27 - 36
9x = -9
x = -9 ÷ 9
x = -1
B) x/3 - 5 = 6
x/3 = 6 + 5
x/3 = 11
x = 11 × 3
x = 33
C) 15 + 3 ( x -7 ) = -30
15 + 3x - 21 = -30
3x + 15 - 21 = -30
3x - 6 = -30
3x = -30 + 6
3x = -24
x = -24 ÷ 3
x = -8
