Use substitution to solve. 2x? = 5 + y 4y = -20 + 8x? solve the first equation for y and substitute it into the second equation. the resulting equation is

Infinite Solutions

Step-by-step explanation:

2x = 5 + y and 4y = -20 + 8x can be solved by substituting one equation into another to find the variables.

2x = 5 + y becomes y = 2x - 5. Substitute this expression into 4y = -20 + 8x.

4(2x - 5) = -20 + 8x

8x - 20 = -20 + 8x

8x - 8x - 20 = -20 + 8x - 8x

-20 = -20

This has infinite solutions since x eliminates and a true statement is left.
