Question

Two equations are given below:

m + 5n = 20
m = n − 4

What is the solution to the set of equations in the form (m, n)?

Answer 1

use substituion
We know the m=n-4 right? So we plug that in place of m in equation 1
n-4+5n=20
solve for n please :)

Answer 2

n=4? @pooja195

Answer 3

good now that we know n=4 we plug that into equation 2 into the place of n
4-4 =?

Answer 4

m=0? @pooja195

Answer 5

yes :) so our answer is?

Answer 6

(0,4) :D @pooja195

Answer 7

yes! :D
