What is 6(3x-1) - 8x = 140 =2(x-1)??

Question

thanks

Answer 1

answer is 18

18x-6-8x=140+2x-2

10x-6=2x+138

8x=144

x=18

Answer 2

Is this written correctly? Or is one of the equals signs supposed to be a plus sign?

Fix it and then I'll answer it.

Have a good day!

Answer 3

6(3x-1) - 8x = 140 =2(x-1)

I think your = signs are off, if you solve for the first half you get

Multiple numbers in () by 6

18x - 6 - 8x = 140

10x  - 6 = 140 (subtract 8x from 18x)

10x = 146 (add 6 to both sides)

x = 14.6 (divide both sides by 10)

Answer 4

you have two equations, 1)   18x-6-8x=140

                            and   2)        2x-2 =140

from eq.(1) 10x=146,x=14.6

from eq.(2) 2x=138,  x=69

so your system of equations are NOT self consistant,let us know how you got these equations,we will be glad to help.GOOD LUCK.

Answer 5

you have to have written this problem incorrectly, because when you simplify, you get 10x-6 = 140 = 2x -2

If 10x-6 = 140, x = 14.6, in which case 140 does NOT equal 2x-2

Answer 6

6(3x-1) - 8x + 140 =2(x-1)

18x - 6 - 8x + 140 = 2x-2

10x + 134 = 2x-2

8x = -136

x = - 17

If the first = is a + and the second = is correct.  Or, if the first = is correct and the second = is a +, then Jessie is correct.
