-4 (-9 +5 = -4)
12 + 5 equals...
It is an algebraic expression which equals a + 28.
13+-12--5 = 6
14w+5 w=5/14
3x+4-2y x=5 and y=-3 You substitute these values into the original equation. 15+4+6 = 25
That will depend on the plus or minus value of 12 which has not been given.
-13 Plug 5 in and multiply it by -5 which equals -25 12 - 25 = -13
12 + 5 equals...
It is an equation in the form of: 3x+5 = 20 and the value of x works out as 5
It is an algebraic expression which equals a + 28.
Just plug in the values for x and y. 4(-1) - 2(5) + (-1)(5) = -19
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.
6
13+-12--5 = 6
14w+5 w=5/14
3x+4-2y x=5 and y=-3 You substitute these values into the original equation. 15+4+6 = 25
5. Just do 9 minus 4. 5 plus 4 equals 9
