Word problem (answer)

you have two equations  x +y = 55   x+4y= 139 substitute the first equation into the second x=y = 55 or x=55-y (55-y) +4y = 139 55+3y= 139 3y= 139-55=64 3y = 64 y =  y=21.3 x=55-21.3 = 33.7      ...

OKay, solve the equation as follows: 1. Add -2 +1 = -1 2. Add +1 to both sides - so you get -2+x>0 3. Add 2 to both sides and this solves the problem x>2
