Question

Z +y – 6; y = 6 and 2 = 2

Answer 1

hello

in this question, we have z + y - 6 = 0

y = 6 and z = 2

substitute z and y into the equation

`\begin{gathered} \text{ z }+\text{ y }-\text{ 6 }=0 \\ y\text{ }=\text{ 6 } \\ z\text{ }=\text{ 2} \\ \text{substitute y and z into the equation} \\ 6\text{ }+\text{ 2 - 6 }=2 \\ \end{gathered}`

the answer is equal to 2

just substitute z and y into the equation
