Let's solve the given equation step-by-step to verify the result.
### Step 1: Write down the Equation
We start with the equation:
[tex]\[ x + 3 = 8 \][/tex]
### Step 2: Substitute the Given Value of [tex]\( x \)[/tex]
The value of [tex]\( x \)[/tex] is given as [tex]\( -15 \)[/tex]. We will substitute this value into the equation:
[tex]\[ -15 + 3 = 8 \][/tex]
### Step 3: Simplify the Left Side
Now, we perform the arithmetic on the left side of the equation:
[tex]\[ -15 + 3 = -12 \][/tex]
### Step 4: Compare Both Sides
After simplifying, we have:
[tex]\[ -12 = 8 \][/tex]
This is a contradiction because [tex]\(-12\)[/tex] is not equal to [tex]\( 8 \)[/tex]. Therefore, given [tex]\( x = -15 \)[/tex], the calculation we performed shows that:
[tex]\[ x + 3 \neq 8 \][/tex]
So, the verified values are:
[tex]\[ \text{Result of } x + 3 = -12 \][/tex]
[tex]\[ \text{Given expected result} = 8 \][/tex]
Hence, for [tex]\( x = -15 \)[/tex], you see that [tex]\( x + 3 \)[/tex] evaluates to [tex]\(-12\)[/tex] while the expected result was [tex]\( 8 \)[/tex], leading to the confirmed solution of [tex]\(-12\)[/tex] on the left side of the equation.
