2x + 7 + 2x = 23
4x + 7 = 23
4x = 16
x = 16/4
x = 4
3x - 12 = -2x + 235x = 35 so x = 7
2x = -7 - 8y
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
If x=4 then 2x+7 =
23
8x-7 plus 2x equals 6 plus 5x plus 2?
X=7
x+7 = 2x 2x = x+7 2x-x = 7 x = 7
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
6x - 8 + 2x - 5 = 7 - 2x ?
2x+3 = 7 2x = 7-3 2x = 4 x = 2
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
