Answer:

X=1

Step-by-step explanation:

1. Since y equals both 2x+5 and 4x+5, you can substitute 2x+5 for y into the first equation.

2. You then have 2x+5=4x+3

3. Then, solve the equation

4. 5=2x+3 (Subtract 2x from both sides)

5. 2=2x (Subtract 3 from both sides)

6. x=1 (Divide both sides by 2)
