Question

5y – 2x = 4 and x = 8.

Answer 1

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.
