How do you solve the system of equations #3x + 4y = 23# and #4x - 3y = 14#?
3 Answers
solve the equations (as u have only 2 variables)
else solve using determinants
Explanation:
multiply first equation by 3
we get
now multiply second equation by 4
we get
add both the obtained equations
we get
hence
now put x = 4 in one of the equations to get y's value
hence
(or)

hope u find it helpful :)
x=5
y=2
Explanation:
Explanation:
A way of solving the system is the following:
1- Isolate
2- Set those two equations as equal, since they are both equivalents to
3- Solver this equation for
4- Now that you know that
5- Once done that, you should get a value for
