Question

Solve the following simultaneous equations
m-2n = -2
m+2n =10

Answer 1

Answer:

m=4 ; n=3

Step-by-step explanation:

We have to add the both equation using the column method.

Answer 2

Answer:

(adding both equations)

2m=8

m=4

(put the value of m in the 2 equation to find the value of n)

m + 2n = 10

4 + 2n = 10

2n = 10 - 4

2n = 6

n = 3

so the value of m = 4

n = 3
