Question

(b) If x = a and y = b is the solution of the equations
x + y = 6 and x - y = 2, then find the values of a
and b.​

Answer 1

Answer:

a = 4 & b = 3

Step-by-step explanation:

solve by elimination

x + y = 6 ......... equation 1

x - y = 2 ......... equation 2

2x = 8

x = 4

put value in equation 1

x + y = 6

4 + y = 6

y = 6 - 4

y = 2
