Question

Javier has a basket of oranges and apples. The number of oranges is 2 more than twice the number of apples in the basket. The difference of half the number of oranges and half the number of apples is 4. An equation created to find the number of apples Javier has in the basket will have .

Answer 1

O=2a+2,  

o/2-a/2=4  this is your system of equations, 

It you wish to solve for apples, then simply substitute o from the first equation into the second equation...

(2a+2)/2-a/2=4  multiply both sides of the equation by 2

2a+2-a=8  combine like terms on the left side

a+2=8  subtract 2 from both sides 

a=6   

So Javier has 6 apples in the basket.
