If x=4 then 2x+7 =
X=7
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
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+3 = 7 2x = 7-3 2x = 4 x = 2
y=f(x)= x(2x+y)=7 f(x)=2x^2 +xy -7 = 0 y=2x^2 +xy -7 y-xy -7 + 2x^2 = 0 y(1-x)=2x^2-7 y=(2x^2-7) / (1-x) Excuse the working. Y equals 2 X squared minus 7 all divided by 1-X
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
2x = -7 - 8y
if you meant 2x²+y²-xy=21x=(±sqrt(-7 y^2+168)+y)/4y=(±sqrt(-7 x^2+84)+x)/2
If x=4 then 2x+7 =
8x-7 plus 2x equals 6 plus 5x plus 2?
X=7
true
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
6x - 8 + 2x - 5 = 7 - 2x ?
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+3 = 7 2x = 7-3 2x = 4 x = 2
