Answer: x = 4
y = 1
Step-by-step explanation:
The given system of simultaneous equations is expressed as
- 5x + 13y = -7 - - - - - - - - - - - - 1
5x + 4y = 24 - - - - - - - - - - - - - 2
The first step is to decide on which variable to eliminate. Let us eliminate x. We would eliminate x by adding equation 1 to equation 2. It becomes
13y + 4y = - 7 + 24
17y = 17
y = 17/17
y = 1
Substituting y = 1 into equation 2, it becomes
5x + 4 × 1 = 24
5x + 4 = 24
5x = 24 - 4
5x = 20
x = 20/5
x = 4
So c=3 years old and a= 25 ml (dose of adults)
so dose of child P=(3/3+12)*25=3/15*25=5 ml
