MATH HELP!!! 2(3x - 4) = -3(x - 8)?
I need help on finding the value of x:
2(3x - 4) = -3(x - 8)
Please check your work once you find x because that is part of my problem

6x-8=-3x+24
9x=32
x=3 5/9 or 32/9
6 x - 8 = - 3 x + 24
9x = 32
x = 32 / 9
CHECK
LHS = 2 (32/3 - 4) = 2 (20/3) = 40/3
RHS = - 3 (32/9 - 72/9) = - 3 (- 40/9) = 40/3
To solve this problem you must solve it in a specific order to get the right answer, the order is called
"PEMDAS "
First solve all the...
1. P.arenthases
Then solve the....
2. E.xponets
Then......
3. M.ultiplecation
4. D.ivision
5. A.ddition
6. S.ubtraction
& you'd get your answer
參考: I know it isnt an answer its just so that you know how to do it.
2(3x - 4) = -3(x - 8)
2*3x - 2*4 = -3*x + 3*8
6x - 8 = -3x + 24
6x + 3x = 8 + 24
9x = 32
x = 32/9
6x - 8 = -3x + 24
9x + 8 = 24
subtract 8
9x = 16
x= 1 7/9
you check the work not me l
try and get x by itself
6x - 8 = -3x + 24 ; distributive property
9x = 32
x = 32/9
Basically you just need to expand by multiplying through and isolate the x to get the answer. So you get:
6x - 8 = -3x + 24
=> 9x = 32
=> x = 32/9
2(3x - 4) = -3(x - 8)
6x - 8 = -3x + 24
9x = 32
x = 32/9
2(3x - 4) = -3(x - 8)
Expand both sides:
6x - 8 = -3x + 24
Add 3x to both sides:
9x - 8 = 24
Add 8 to both sides:
9x = 32
Divide by 9:
x = 32/9
CHECK:
2(3(32/9) - 4) = -3(32/9 - 8)
2(32/3 - 4) = -3(-40/9)
2(20/3) = 40/3
40/3 = 40/3
CHECK
