Question

The solutions for the equations x–y=4 and x+y=10 are

Answer 1

Step-by-step explanation:

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
