Given Equation is y = 4x - 7 --------- (1)
Given Equation is 16x - 5y = 25 ----- (2)
Substitute (1) in (2), we get
16x - 5(4x - 7) = 25
16x - 20x + 35 = 25
-4x = 25 - 35
-4x = -10
x = 5/2.
Substitute x = 5/2 in (1), we get
y = 4x - 7
y = 4(5/2) - 7
= 10 - 7
= 3.
Therefore x = 5/2, y = 3
Hope this helps!
