3x - 7 = 5x - 13
-3x -3x
5x - 3x = 2x
-7 = 2x - 13
+7 +7
-13+7 = -6
2x = -6
2x/2 = -6/2
x = -3
Answer: x = -3
dy/dx = 2xy
dy/y = (2x)dx
INT(1/y)dy = INT(2x)dx
ln y + c = x^2 + d
ln y = x^2 + constant
y = e^(x^2 + constant)
1 = e^constant ... so constant=0 ... so y = e^(x^2)
Verification:
y = e^(x^2)
dy/dx = 2x*e^(x^2) = 2xy
<span>and e^(0^2) = e^0 = 1
