यदि `[(x+3,z+4,2y-7),(4x+6,a-1,0),(b-3,3b,z+2c)]=[(0,6,3y-2),(2x,-3,2c+2),(2b+4,-21,0)]` a, b, c, x, y तथा z का मान प्राप्त करे ।

Explanation

चूँकि दिए हुए मैट्रिक्स बराबर हैं । अत: उनके संगत अवयव समान होंगे । इसलिए
`{:(x+3=0," "...(i),z + 4 = 6","," "...(ii)),(2y-7=3y-2," "...(iii),4x + 6 = 2x","," "...(iv)),(a-1=-3," "...(v),0=2c+2," "...(vi)),(b-3=2b+4," "...(vii),3b = -21," "...(viii)),(z+2c=0," "...(ix),,):}`
(i) से, x = -3, (iii) से y = -5 तथा (ii) से, z = 2
(v) से, a = -2 (viii) से b = -7 तथा (vi), से c = -1
इस प्रकार a = -2, b = -7, c = -1, x = -3, y = -5, z = 2
