What is the solution of the equation x 8 = 17?
A. -9
B. 9
C. 25
D. 27

If the symbol between x and 8 is positive, then: x + 8 = 17; x = 17 - 8; x = 9 *************** If the symbol between x and 8 is negative, then: x - 8 = 17; x = 17 + 8; x = 25

If the symbol between x and 8 is positive, then:

x + 8 = 17;

x = 17 - 8;

x = 9

***************

If the symbol between x and 8 is negative, then:

x - 8 = 17;

x = 17 + 8;

x = 25

x + 8 = 17;

x = 17 - 8;

x = 9

***************

If the symbol between x and 8 is negative, then:

x - 8 = 17;

x = 17 + 8;

x = 25

What is 1/3x 5 = 12? -3x = 4 - 5; -3x = -1; x = 1/3 **Weegy:** 1/3x+5=12
subtract 5 from each side so you get 1/3x=7; now multiply by 3/1 to each side
(3/1)(1/3x)=7(3/1)
x=21
A=2r+8
subtract 8 from each side so you get
a-8=2r; now divide by 2 to isolate r so you get
a/2-4=r. [ ] (More)

1/3x+5=12;

x/3 + 5 = 12;

x/3 = 12 - 5;

x/3 = 7;

x = 7 * 3;

x = 21

x/3 + 5 = 12;

x/3 = 12 - 5;

x/3 = 7;

x = 7 * 3;

x = 21
