This is an unclear equation, actually some sort of addition.
(Opposite means negative? Inverse?)
2x + x + (-x) + (-1) = 7 + 2 (-x) ??
2x - 1 = 7 - 2x
4x = 8
x = 2
-2x plus 3y equals 1
NM equals 2x + 1, as stated in the question!
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
x equals 4
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
x=1
x = 0
-2x plus 3y equals 1
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
NM equals 2x + 1, as stated in the question!
Y = 2x + 1
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
x equals 4
No they are parallel.
Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined. In this case, the opposite of 2x + 1 is -(2x + 1) = -2x - 1 by the distributive property. Adding like terms, 2x + -2x + 1 +-1 = 0 + 0 = 0.
2x + 1 = 13; 2x = 12; x = 6
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
