What is 16 plus 2x?
16+2x can not be simplified any further. 16+2x would normally be written as 2x+16 to keep the degrees of the terms in order from highest to lowest.
If 2x plus 4 equals 16 then x is what?
2x + 4 = 16 2x = 16 - 4 2x = 12 x = 12/2 x = 6
How do you solve 2x-5 equals 11?
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
What is the ordered pair for 2x plus 4y equals 16 and 2x-4y equals 0?
2x + 4y = 16 <=> 2x + 4y - 16 = 0 2x - 4y = 0 2x - 4y = 2x + 4y - 16 -8y = -16 y = 2 Substituting the known value for y in either of the original equations enables x to be determined. 2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4 2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4. The ordered pair satisfying both equations is (4,2)
(2x-1)(x plus 16)?
It is equivalent to: 2x^2 +31x -16
What is the answer of 8x plus 16 equals 6x?
8x + 16 = 6x -> 2x + 16 = 0 -> 2x = -16 -> x = -8
Why is -2 raised to the power 4 equal -16 but when -2 is multiplied 4 times (-2x-2x-2x-2) it is 16?
-2 to the 4th power is 16.
What is the answer to 5-2x equals 16-4x?
5 - 2x = 16 - 4x ie 4x - 2x = 16 - 5 ie 2x = 11 ie x = 5.5 Check: does 5 - 11 = 16 - 22? Yes, both = -6.
2x 4 16 then x is?
2x + 4 = 162x + 4 - 4 = 16 - 42x = 122x/2 = 12/2x = 6
