Question

Solve each system by elimintaion. x-y=11 2x+y=19

Answer 1

Answer:

X - Y = 11 -------1

2x + y = 19 --------2

Solving by elimination method

Multiple equation 1 by 2

2( X - y )= 22

2x - 2y = 22

2x + y = 19

Y = 3

Putting value of y= 3 in equation 1

X - 3 = 11

X = 11 + 3

X = 14

Value of X = 14 and Y = 3
