Question

solve 4m - 19n =450 ; 5n+m=96

Answer 1

Answer:

m=1358/13

n=-22/13

Step-by-step explanation:

solving by simultaneous linear equation

Answer 2

Step-by-step explanation:

4m - 19n = 450...(1)

5n + m = 96

Rearrange

m + 5n = 96

Multiply entire equation by 4.

4m + 20n = 384...(2)

Subtracting (2) from (1)

4m - 19n = 450

-4m - 20n = - 384

-39n = 66

n = - 22 / 13

Substitute in m + 5n = 96

m - 110 / 13 = 96

m = 96 + 110 / 13

m = 1248 + 110 / 13

m = 1358 / 13
