Question

solve graphically x+y=10 and x-y=4​

Answer 1

Here is your answer mate..


[ // Solve equation 2 for variable x in equation (1) ]

[1] ( y + 4 ) + y = 10

[2] 2y = 10 - 6 = 4


[ // Solve equation (1) for the variable y ]


[1] 2y = 6

[1] y = 6/2 = 3


// By we know this much:

x = y + 4

y = 3

// Use the y value to solve for x

x = (3 + 4 ) = 7



Solution ..

x = 7
y = 3

Answer 2

Answer:

x+y=10    1

x-y=4      2

add equation 1 and 2

2x=14

x=7

we put x=7 in the equation no 1

7+y=10

y=10-7

y=3
