(x , y) → (5, 9)
Since both equations express y in terms of x we can equate them
7x - 26 = 4x - 11
subtract 4x from both sides
7x - 4x - 26 = - 11
3x - 26 = - 11
add 26 to both sides
3x = - 11 + 26 = 15
divide both sides by 3
x = [tex]\frac{15}{3}[/tex] = 5
substitute x = 5 into either of the 2 equations for y
y = (4 × 5) - 11 = 20 - 11 = 9
solution is (5, 9)
