If x=4 then 2x+7 =
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
2x - 7 = 15 2x = 22 x = 11
2x-9=7 2x=16 X=8
2x+3 = 7 2x = 7-3 2x = 4 x = 2
6x - 8 + 2x - 5 = 7 - 2x ?
2x-6=7, x=?
2x = -7 - 8y
It equals 7 since 2x = 7+x where 2 has 2x but 7 is one x because there is only one x . So it is 7.
x+7 = 2x 2x = x+7 2x-x = 7 x = 7
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
