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.
-3
That will depend on the plus or minus value of 12 which has not been given.
12/4=3 3 is not a value of 5
It is 12*(5 - 3).
It is 12*(5 - 3).
8
your expression is this... n+5=3+12 n+5=15 n=10
-13 Plug 5 in and multiply it by -5 which equals -25 12 - 25 = -13
-3 - 4 - 5 rewrite as, -3 + (-4) + (-5) = - 12 PS this is an expression, not an equation
(5×3)÷2
