Question

Solve the equation: x(1,1) + y(1,-1) = (7,3)​

Answer 1

Answer:

x = 5, y = 2

Step-by-step explanation:

X(1,1) + y(1,-1) = (7,3)

(x,x) + (y,-y) = (7,3)

x + y = 7 -> equation 1

x - y = 3 -> equation 2

x = y + 3

Substituting value of x in equation 1 we get

(y + 3) + y = 7

2y + 3 = 7

2y = 7 - 3

2y = 4

y = 2

Substituting value of y equation 1 we get

x + y = 7

x + 2 = u

x = 7 - 2

x = 5

Therefore x = 5 and y = 2
