find the solutions for the pairs of equation. and identify the solution 5x+3y=15and 5x+2y=10

If x = a and y=b is the solution of the pair of equation x-y =5 and x+y =3, find 'a' and 'b'.

Find the value of lambda the equation is 5x+y+lambda=0 where x=1 and y=5

The values of lambda for which the system of equations x + y - 3 = 0 (1+lambda)x+(2+lambda)y-8=0 x-(1 +lambda) y + (2 + lambda) = 0 is consistent are a) -5//3,1 b) 2//3,-3 c) -1//3,-3 d)0,1

Find the value of lambda the equation is 2x+3y+lambda where x=2 and y=1

If the system of equations 2x-3y+4=0,5x-2y-1=0 and 21x-8y+lambda=0 are consistent,then lambda is
