Question

Any answers: 10+X-(2-3X)=4 Solve for X

Answer 1

10 + x - 2 + 3x = 4

Answer 2

x=-1

Answer 3

4x = -4

Answer 4

x = -1

Answer 5

4x = -4 x = -1

Answer 6

hi folks, if you do the problem in the parenthes?? first, then start at the beginnng and work your way to the right, -1 does not work. Or am I wrong?

Answer 7

u mean when ur replacing value of x or when u need to find it

Answer 8

Yes it does.
10+(-1)-(2-3(-1))=4
10-1-(2+3)=4
10-1-5=4
10-6=4
4=4

Answer 9

Show how you did it so we can narrow down where the problem lies.

Answer 10

I did the (2-3X) first, when replacing X with -1, this part of the problem becomes 2-
-3 =-1. then 10 + -1=9- -1 = 8, not 4

Answer 11

Inside the parenthesis you have (2-3x)
Since x=-1 3x means 3*(-1) so 3x=-3
Now (2-3x) becomes (2-(-3)) So that is (2+3) So inside the parenthesis it's 5

The key seems to be: 2-(-3)=2+3=5
Two minuses give you a plus sign.

Answer 12

Rudy's Right

Answer 13

OK, I guess I am not understanding, Youhave a positive number 2 and you are taking away -3 from that gives you a negative number -1. Why?

Answer 14

2-3=-1
But you don't have that. You have 2-(-3) and two negatives make a positive. So your:
2-(-3) is the same as 2+3 Which is 5

You had (2-3x) But the x=-1 So if you multiply 3*(-1) all it does is switch the sign of the 3.
So from (2-3x) it goes to (2+3)

Answer 15

- -3

5
