rearrange the equation X+6y=18 to x=18-6y to get x by itself sub x into the other equation and solve for y 2(18-6y)-3y=-24 y=..... then sub the y value back into x= 18-6y to get what x is x=18-6(....)

Consider the curve given by the equation ln(y + x + 3) = xy + y3. Find an equation of the tangent line at the point (?4, 2)

**calculus**

dt/dx= ((x^2+a^2)^(1/2))/v1+((b^2+d^2)^(1/2))/v1 the function dt/dx has a zero at a unique x on (0,d). Use this to justify your discovery that d= (x^2+a^2)^(1/2) + (b^2+d^2)^(1/2)
