If 2x+z=2y and 2x+2y+z=20 what is the value of y?

Answers

$2x+z=2y\to2x=2y-z\n\nsubstitute\ to\ 2x+2y+z=20:\n\n(2y-z)+2y+z=20\n2y-z+2y+z=20\n4y=20\ \ \ \ /:4\ny=5\to answer$

The value of y is 5

Given,

2x+z=2y

2x+2y+z=20

Now,

From equation substitute the value of 2x,

2x = 2y -z

substitute the value in second equation,

2y -z + 2y + z = 20

Now solve the terms with like variables,

4y = 20

y = 5
