Determine the value of y, if x is 4 . y=(21)/(x-7) Answer:

Substitute x into equation: Substitute the value of x into the equation. We are given y = (21)/(x-7) and we need to find the value of y when x is 4. Substitute x = 4 into the equation. y = (21)/(4-7)Perform subtraction in denominator: Perform the subtraction in the denominator. Calculate the value inside the parentheses (4-7). y = (21)/(-3)Divide numerator by denominator: Divide the numerator by the denominator. Now, divide 21 by -3 to find the value of y. y = 21 / -3 y = -7

Q. Determine the value of

y

, if

x

4

\newline

y=\frac{21}{x-7}

\newline

Answer:

Substitute $x$ into equation: Substitute the value of $x$ into the equation. $\newline$ We are given $y = \frac{21}{x-7}$ and we need to find the value of $y$ when $x$ is $4$ . $\newline$ Substitute $x = 4$ into the equation. $\newline$ $y = \frac{21}{4-7}$
Perform subtraction in denominator: Perform the subtraction in the denominator. $\newline$ Calculate the value inside the parentheses $(4-7)$ . $\newline$ $y = \frac{21}{-3}$
Divide numerator by denominator: Divide the numerator by the denominator. $\newline$ Now, divide $21$ by $-3$ to find the value of $y$ . $\newline$ $y = \frac{21}{-3}$ $\newline$ $y = -7$
