Question

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

Answer 1

Answer:

a= 3 , b= 1

Step-by-step explanation:

a-b= 2

a+b= 4

please mark me as brainliest LoL

Answer 2

Answer:

$\huge\fcolorbox{cyan}{black}{\color{blue}{★solution★}} \\ given, \\ x - y = 2...(i) \\ and \: x + y = 4...(ii) \\ adding \: (i) \: and \: (ii), we \: get \\ 2x = 6 \\ ⟹ x = 3 \\ ⟹a = 3 \\ putting \: x = 3 \: in \: (ii), we \: get \\ y = 4 - x = 4 - 3 = 1 \\ ⟹b = 1 \\ \\ hence , a = 3, b = 1$
