(x1, x2) = (3, -4)

Step-by-step explanation:

As with any 2-step linear equation, subtract the constant, then multiply by the inverse of the coefficient of the variable.

Performing the multiplication of the matrix by the vector gives the solution.

x = ((5)(1) +(-2)(-5))/5 = 15/5 = 3

y = ((-5)(1) +(3)(-5))/5 = -20/5 = -4

Using your variables, x1, x2, the solution is …

(x1, x2) = (3, -4)
