Answer:
x+y/4 = 1/2
x-3y/3 = 2
move variables to one side:
multiply the first equation by 4 to get: x+y =2
and the second equation by 3 to get: x-3y =6
then subtract the equations to cancel out x:
x+y = 2
- x-3y = 6
then u get
y--3y = 2-6
4y = -4
y=-1
substitute to solve for x:
x-1 / 4 =1/2
x-1 = 2
x=3
check:
3+-1
2/4= 1/2
correct!!!

Answer:
16 hours.
Step-by-step explanation:
There is 30 days in a month, if Robin takes 3 hours to mow the lawn and does this four times a month that would be 12 hours, if she takes 1 hour to pull weeds and does this 4 times as well that would be 4. 4+12 would equal 16 hours.
