1 answer:
Answer:
All real numbers
Step-by-step explanation:
Since x=2y+5, and 2x-4y=10, substitute 2y+5 for x into 2x-4y=10
2(2y+5)-4y=10
Use distributive prop.
4y+10-4y=10
10=10
Since both sides of the equation are always equivalent,
All real numbers work, since the two equations are the same line.
