Question

please help me solve it !!​

Answer 1

Answer:

Step-by-step explanation:

x+y = 7  ----(1)

x-y  = 2  -----(2)

adding (1) and (2)

2x = 9

x= 4.5

y = 2.5

Answer 2

Answer:

x = 4.5 y = 2.5

Step-by-step explanation:

x + y = 7  

x - y = 2

first we add the equations

x + y + x - y = 7+2

2x = 9

x = 4.5

now constitute the value of X and find Y

4.5 + y = 7

y = 7 - 4.5

y = 2.5

for verifying :

4.5 - 2.5 =  2
