Answer» B=1 A = 17 B=1and A=17 A+B=18‐‐‐1A-B=16---2(Adding eq1 and eq2)2A=34A=17(Putting the value of A in eq1)17+B=18B=18-17B=1:-A=17 and B=1By elimination method A+B=18---1 +A-B=06=2A=24A=24÷2A=12 Putting value in eqñ-112+B=18B=18-12 B=6This method is called elimination method of solving pair of linear eqñ in two variables |
