Question

Given the equation 6x-y=98, find x if y=-2

Answer 1

x=16

Explanation

given the function

$6x-y=98$

Step 1

as we need x is terms of y, let's solve for x

$6x-y=98$

a) add y in both sides

$\begin{gathered} 6x-y+y=98+y \\ 6x=98+y \end{gathered}$

b) divide both sides by 6

$\begin{gathered} 6x=98+y \\ \frac{6x}{6}=\frac{98+y}{6} \\ x=\frac{98}{6}+\frac{y}{6}\Rightarrow equation \\ \end{gathered}$

Step 2

now, evaluate for y=-2

$\begin{gathered} x=\frac{98}{6}+\frac{y}{6}\operatorname{\Rightarrow}equat\imaginaryI on \\ replace \\ x=\frac{98}{6}-\frac{2}{6} \\ x=\frac{96}{6}=16 \\ x=16 \end{gathered}$

therefore, the answer is

x=16
