Question

solve by eliminatiom method 10m+2n=4
15m-5n=-2
​

Answer 1

HOLA...!!!

10m+2n=4....(1)

15m-5n=-2...... (2)

Multiplying equation 1 by 5 and equation 2 by 2 .

50m+10n=20..... (3)

30m-10n=-10...... (4)

Adding equation 3 and 4.

50m+10n=20

+ 30m-10n=-10

__________________

80 m =10

➡m=8

Substituting value of m in equation 3 ,

30 (8)+10n=20

240+10n=20

10n=20-240

2n=-220

n=-220÷2

➡n=-110
