Step-by-step explanation:
2x + y = 21
Solving
2x + y = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
2x + y + -1y = 21 + -1y
Combine like terms: y + -1y = 0
2x + 0 = 21 + -1y
2x = 21 + -1y
Divide each side by '2'.
x = 10.5 + -0.5y
Simplifying
x = 10.5 + -0.5y

The answer will most likely be 56 degrees try that it should be the answer!
Consecutive integers have similar characteristics in such a way that their difference is their differences is always one. For example, 1,2,3...
the difference between the consecutive integers is 1. therefore if the first integer is n, the next one will be:
n, (n+1),(n+1+1),...
this will give us:
n,n+1, n+2,......
the answer is:
1. n, n+1, n+2,.....
