Question

Solve by cross multiplication method:
4u-v=4 , 3u+2v=14

Answer 1

4X - Y = 4 .............(1)

3X + 2Y = 14.........(2)

HERE,

A1 = 4 , A2 = 3 , B1 = -1 , B2 = 2 , C1 = -4 , C2 = -14.

THEREFORE BY CROSS MULTIPLICATION METHOD,

X/ B1C2-B2C1 = Y/C1A2-C2A1 = 1/A1B2-A2B1.

X/ (-1× -14) -( 2×-4) = Y/(-4×3)- (-14×4) = 1/(4×2) × (3×-1) .

. SOLVE YOU WILL GET THE VALUE OF X AND Y..
