What does x equal? 5x - 13 = 8x + 20?

Question

i've been sitting here for an hour doing guess/check. it's not working. x = -13 was the closest I got... plz help!

Answer 1

5x - 13 = 8x + 20, subtract 8x from both sides and add thirteen to both sides

5x - 8x = 13 + 20, now simplify

-3x = 33, now divide 33 by -3

x = -11

Answer 2

Step 1.
5x -13 = 8x + 20 subtract 20 from both side

Step 2.
5x - 33 = 8x subtract 5x from both sides

Step 3.
-33 = 3x divided both sides by 3

Step 4. -11 = x

Answer 3

5x - 13 = 8x + 20
-5x -13 = -5x + 20

- 13= 3x+ 20
-20 = 3x - 20

-33 = 3x

-33 ÷3= -11 3x ÷ 3= x

x = -11

Answer 4

the first thing you want to do is isolate the x so you add 13 to both sides and subtract 8x from both sides
5x - 13 = 8x + 20
-8x+13 -8x +13
you get
-3x = 33

You then divide both sides by 3

-3x = 33
/-3 /-3

and 33 / -3 equals 11 so

x = 11

Answer 5

5x - 13 = 8x + 20, do the cross overs...
5x - 8x = 20 + 13
-3x = 33
x = 33 / -3
x = -11

test it:
5x - 13 = 8x + 20
5(-11) - 13 = 8(-11) + 20
-55 - 13 = -88 + 20
so, -68 = -68

Answer 6

5x - 13 = 8x + 20

1st step : put the 'x' variable together

5x - 8x = 20 +13

-3x = 33

x= -11

Answer 7

5x -13 = 8x + 20

5x - 8x = 13 + 20

-3x = 33

x = -11

Answer 8

5x-13=8x=20
5x-8x=20+13
-3x=33
3x=-33
-33
x= __ =-11
3
x= -11

Answer 9

Guess/check - try calculate
5x - 13 = 8x + 20
5x-8x = 13+20
-3x = 33
x = -11

This is not hard. Do yourself a favor and learn how to do it.

Answer 10

5x-13=8x+20
=> 5x-8x=20+13
=> -3x=33
=> -(-3x)= -(33)
=> 3x= -33
=> 3x/3= -33/3
=> x= -11
