Question

solve the simultaneous equation. 10m + 2n = 4 ; 4m + n = 3​

Answer 1

Answer:

10m+2n=4

4m+n=3

we, are using elimination method here.

Step-by-step explanation:

$10m + 2n = 4$

$(4m + n = 3) \times 2$

$8m + 2n = 6$

10m+2n=4

8m+2n=6

(-) (-) (-)

$2m = - 2$

$m = - 1$

$then \: sbstitute \: m \: value \: in \: an y \: equation$

10m+2n=4

10(-1)+2n=4

-10+2n=4

2n=4+10

2n=14

n=14/2

n=7

$m = - 1and \: n = 7$
