Substitution method is one of the way in determining the value of a variable by substituting the variable by the value of an equation and simplifying its value. So in step by step way, 7x-5(2x-4) is the equation result in substituting the Y variable. By simplifying the value of x is 3.34 and Y is 2.68

Substitute y= 2x - 4 into 7x - 5y = 14.

> 7x - 5(2x - 4) = 14
> 7x - 10x + 20 = 14
>  -3x = -6
> x = 2

Now sub x = 2 back into y= 2x - 4 to find what y equals.

> y = 2(2) - 4
> y = 4 - 4 
> y = 0

Therefore, x = 2 and y = 0.
