Question

4m+3n=1 ; 8m-9n=7
can anyone help me? ​

Answer 1

Answer:

n = - 1/3

m = 1/2

Step-by-step explanation:

Multiplying the first equation by 2,

2(4m + 3n) = 2*1

8m + 6n = 2

Now subtracting both of them,

8m + 6n = 2

- 8m - 9n = 7

———————

0m - 15n = -5

15n = -5

n = -5/15

n = - 1/3

Substituting n = -1/3,

4m + 3n = 1

4m + 3(-1/3) = 1

4m - 1 = 1

4m = 2

m = 2/4

m = 1/2
