A%2BB=3
A-B=11
Add the equations,
A%2BB%2BA-B=3%2B11
2A=14
A=7
Then,
7%2BB=3
B=-4

we are given two equations in two unknowns,
x + y = 3
x - y = 11
add the two equations
2x = 14
x = 7, y = -4
********************
check answer by substituting for x and y in second equation
7 - (-4) = 11
7 + 4 = 11
11 = 11
our answer checks
