The answer heavily depends on the value of 'x' ... a piece of information that the
question neglects to mention.
Not only will the value of 'x' completely determine the value of the given expression,
but in addition, any change in the value of 'x' will cause a change in the value of the
expression instantaneously, in less than the Planck quantum of time, with not an iota
of propagation lag or latency whatsoever.
The variables have no known values and as an expression it is: 5x+9y+5
5x=4012y=84124
If you mean 5x+2 = 12 then 5x = 10 and the value of x is 2
The given expression can be simplified to: 12-6x
If you mean: 3+5x+7 = 70 then the value of x is 12
That will depend on the plus or minus value of 12 which has not been given.
The variables have no known values and as an expression it is: 5x+9y+5
-42
-13 Plug 5 in and multiply it by -5 which equals -25 12 - 25 = -13
5x=4012y=84124
If you mean 5x+2 = 12 then 5x = 10 and the value of x is 2
The given expression can be simplified to: 12-6x
It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
Expression
The expression is: 6-5x when simplified
If you mean: 3+5x+7 = 70 then the value of x is 12
3 + 5x is the simplest expression of this problem.
