Diketahui 14.00 wita jam berapa jika wib

Answer (4)

This is beautiful.
-m+2n=9 .....(i) 4m=3n-14 .....(ii)
We are going to use elimination method. Rearrange the equations so that the m and n are on same vertical sides.
-m+2n=9 .....(i) (multiply by 4) 4m -3n=-14 ........(ii)
We multiply both sides of equation i by 4, because of the 4 attached to the m in equation (ii)
4*(-m+2n)=4*(9) ...................(i)
-4m + 8n = 36 ............(iii)
Add equations (ii) and (iii)
4m+(-4m) -3n+8n = -14 +36 4m-4m +5n = 22 5n = 22
Divide both sides by 5.
n = 22/5 = 4.4.
Now let us solve for m.
From:
-m+2n=9 .....(i) Let us substitute the solved value of n = 4.4
-m + 2(4.4) = 9 -m = 9 - 8.8 -m = 0.2 Multiply both sides by -1.
m = -0.2
Therefore m = -0.2, n = 4.4.
Hurray!

The solution to the system of equations − m + 2 n = 9 and 4 m = − 3 n − 14 is m = − 5 and n = 2 .
