If x = a and y = b is the solution of the equations x -y = 2 and x+y = 4, then the values of a and b are, respectively.

Question

Philoid · Accepted Answer

Solving the equations -

x - y = 2 and

x + y = 4;

adding them,

2x = 6

x = 3;

subtracting them,

2y = 2

y = 1;

so, a = 3 and b = 1 is the solution of the equations.
