Answer:
Step-by-step explanation:
Your car breaks down unexpectedly and you must have it repaired immediately. That's an example of a situation where you might use money from a financial reserve.
The standard form: ax + by = c
and your equation is: -2x + 3y = - 5 (Yes this is written in standard form)
First exercise
Given
We can cross multiply this equation to get
Expand both terms:
Subtract 2x from both sides:
Subtract 3 from both sides:
Divide both sides by 7:
Second exercise
Let be the number of pine, oath and ash trees. We are given:
We can substitute the expression for p of the first equation in the last equation to get
Now we use the second equation, to express o in terms of a:
