How do you solve #x-2y=4# and #8y+24x=5# using substitution?
1 Answer
Explanation:
Given:
The Substitution solving method tells us that it's possible to find the value of one of the two variables from one of the two equations, then substitute it in the other one.
In your excercise it's easy to find
Now we can substituite it in
Now we can substitute the
In a graph the system solution is the point where
graph{(x-2y-4)(24x+8y-5)=0 [-3.347, 6.52, -4.167, 0.766]}
