Question

x+y = 10 x-y = -4 then x^2 is ​

Answer 1

Answer:

x+y=10

x-y=-4

2x = 6

+y and -y will be cancelled .

2x=6

x=6/2

x=3

Answer 2

Answer:

Given⤵

➡x+y= 10 and x-y= -4

To find ⤵

➡Value of x².

Solution⤵

⚫Let the equation

x+y= 10 ... (i)

x-y= -4 ... (ii)

⚫Adding the equation (i) and (ii), we get

x+y= 10

x-y= -4

________

➡ 2x=6

➡x= 6/2

➡x= 3

⚫Therefore x² ... (iii)

⚫Substituting the valtof x= 3 in equation (iii)

➡3² or 3×3

➡9

✅Hence, the value of x² is 9.
