firstly remove the bracket
4y-18+y+14+6*11=180
collect like terms
4y+y-18+14+66=180
5y +62=180
5y =180-62
5y=118
divide both side by 5
5y/5=118/5
y=23.6
The answer would be x^2 - 2x -8
The way the equation is written
Solve for G:F = (G m^3)/r^2
F = (G m^3)/r^2 is equivalent to (G m^3)/r^2 = F:(G m^3)/r^2 = F
Divide both sides by m^3/r^2:Answer: G = (F r^2)/m^3
