What r the answers to...?

3(x-4)=15

x+ 5/8= -3/8

note / means fraction bar

Answer 1

1.
3(x - 4) = 15
Multiply out:
3x - 12 = 15
Add 12:
3x = 27
Divide by 3:
x = 9.

2.
You need to use brackets when writing a fraction on a single line if there are several terms in the numerator or the deonominator. I am guessing that your equation is really:
(x + 5) / 8 = -3/8
Multiply by 8:
x + 5 = -3
Subtract 5:
x = -8.

However, if it is as you have written it:
x+ 5/8= -3/8
Subtract 5/8:
x = -5/8 - 3/8
= -(5 + 3) / 8
= -8 / 8
= -1.

Answer 2

The Answers are:

1. 3(x-4)=15
distribute the 3 first to give you
3x-12=15
add 12
3x=27
divide 3
x=9

2. x+5/8=-3/8
subtract 5/8
x= -1

Answer 3

OK, for
3(x-4)=15
divide through by 3, to get

x-4 = 5

then add 4 to both sides to give
x -4+4 = 5+4

x =9

for

x+ 5/8= -3/8

subtract 5/8 from each side, to give

x + 5/8 -5/8 = -3/8 -5/8

or

x +0 = -1

x = -1

Answer 4

3(x-4)=15
3x-12=15 +12=+12 3x=15+12
3x= 27
3x/3=27/3
x=9 (answer)


x+5/8= -3/8
-5/8 = - 5/8
x= -5/8 - 3/8
x= -8/8=
x= -1(answer)

Answer 5

3(x-4)=15
x-4=5
x=9

x+5/8=-3/8
x=-8/8=-1

Answer 6

3(x-4)=15
3x-12=15
3x-12+12=15+12
3x=27
x=9

x+5/8=-3/8
x+5/8-5/8=-3/8+-5/8
x= -1
