Hi
2/3 y+y-4=31
Simplify both sides of the equation
2/3 y-4=31
Combine like terms
(2/3 y+y)+(-4)=31
5/3 y-4=31
Add 4 to both sides
5/3 y-4+4=31+4
5/3 y=35
Multiply both sides 3/5
(3/5)*(5/3 y)=(3/5)*35
y=21
I hope that's help !
Answer:
x = 114
Step-by-step explanation:
180 - 105 = 75
39 + 75 = x
x = 114
Just remember, for y, just leave the dy/dx there
3x²+3(2xy+x²dy/dx)+3y²dy/dx=0
3x²+6xy+3x²dy/dx+3y²dy/dx=0
minus (3x²+6xy) from both sides
3x²dy/dx+3y²dy/dx=-3x²-6xy
undistribute dy/dx
dy/dx(3x²+3y²)=-3x-3xy
divide both sides by (3x²+3y²)
