Answer:
y = 4 is the correct solution.
Explanation:
If x = 8, then we can plug this into the equation 5y – 2x = 4 to solve for y:
5y – 2(8) = 4
5y – 16 = 4
5y = 20
y = 4
Therefore, the solution to the system of equations 5y – 2x = 4 and x = 8 is y = 4.
We can check our answer by substituting y = 4 into the original equation:
5(4) – 2x = 4
20 – 2x = 4
-2x = -16
x = 8
Since x = 8 is a solution to the original equation, we can confirm that y = 4 is the correct solution.
