If x^2-y^2=55 and x-y=5 then what is the value of x

See below

Step-by-step explanation:

1.    x²-y²=55           or         (x+y)(x-y)=55  

2.   x-y=5

Solution      (1)    (x+y)5=55

     (2)    x+y=55/5

     (3)    x+y=11

     (4)    x+y+x-y=11+5       The equation we got before we can use now

     (5)    2x+y-y=16            see this y-y=0

     (6)    2x=16                   2x+0=16 that's mean 2x=16

     (7)    x=8                       Got the answer

Hope that help
