Let x years ago.
59−x=7(11−x)
59−x=77−7x
6x=18
x=3

The ordered pair (- 3, 1 ) is a solution to the second equation because it makes the second equation true
To test , substitute the coordinates of (- 3, 1) into the equations and if both sides are true then it is a solution to the equation.
x - 4y = - 3 - 4 = - 7 ≠ 6 ← not true
(3 × - 3) + 1 = - 9 + 1 = - 8 ← true
Thus (- 3, 1 ) is a solution to the second equation
