Solution
The expression given is: 5y/22 - x + 4(x - 1) - y
-
How many terms are there in the expression? There are four terms in the expression. They are 5y/22, -x, 4(x - 1), and -y.
-
What is the value of the coefficient of y? There are two terms with y. The coefficients are 5/22 and -1.
-
For what value of x is the expression undefined? The expression would be undefined if the denominator in any fraction becomes zero. However, there are no terms with x in the denominator. Therefore, the expression is defined for all real numbers x.
