Answer:
6
Step-by-step explanation:
2 times the difference of a number and 1 = 4 plus that number
In other to express the word problem Mathematically ; let the number = x
2(x - 1) = 4 + x

Answer:
x=3, y=5
Step-by-step explanation:
To find x:
Because opposite sides of a parallelogram are congruent, we can set up the equation 2x+5=12x-25. Solving the equation will show that x=3.
To find y:
Using the same method as x, we can find that y=5.
Hope this helped!
Answer:
