Question

1. y = x + 2

x = -3 solution? ( -3 , 1 )

explain your answer here:

Explanation:

Step1: Substitute \( x = -3 \) into \( y = x + 2 \)

We know the equation \( y = x + 2 \) and the value of \( x \) is \( -3 \). Substitute \( x=-3 \) into the equation: \( y=-3 + 2 \).

Step2: Calculate the value of \( y \)

Simplify the right - hand side of the equation \( y=-3 + 2 \). According to the rule of addition of integers, \( -3+2=-1 \). But the given \( y \) - value in the point \( (-3,1) \) is \( 1 \), which is not equal to \( -1 \).

Answer:

The point \( (-3,1) \) is not a solution of the system of equations \(

$$\begin{cases}y = x + 2\\x=-3\end{cases}$$

\) because when \( x = - 3 \) is substituted into \( y=x + 2 \), we get \( y=-3 + 2=-1
eq1 \).
