CBSE Class 10 Maths Pair of Linear Equations in 2 Variables
 Five years ago Nuri was thrice as old as Sonu. Ten years later Nuri will be twice as old as Sonu. How old are Nuri and Sonu?
 5x 4y + 8 = 0 7x +6y 9 =0

find the value of a and b
 A and B, each has a certain amount (in ₹). If A gives ₹40 to B, both will have equal amounts. If B gives ₹110 to A, A will have 4 times the amount left with B. What is the initial amount with B?
 3x/25y/3=2 x/3+y/2=13/6 by elimination method

2ax+3by=(a+2b)
3ax+2by=2(a+b)

how to solve it
 If the linear equation in two variables 2x –y = 2, 3y –4x = 2and px–3y = 2are concurrent, then find the value of p
 If ܽa + b = 35 and a − b = 13, where a > b, then find the value of a and ܾb.
 Solve the system of linear equations by elimination method 2/3x+3/4y=1/12;3x/42/3y=1/2
