Answer:
The first step to solving the equation is:
[tex]3x+24 = 42[/tex]
Hence, 3x + 24 = 42 is the correct option.
Step-by-step explanation:
Given the equation
[tex]3(x+8)= 42[/tex]
First of all, we need to apply the distributive law on the left side of the equation to expand the equation.
[tex]\quad \:a\left(b+c\right)=ab+ac[/tex]
So the equation would be expaneded using the distributive law on the left side of the equation
[tex]3(x+8) = 42[/tex]
[tex]3x+24 = 42[/tex] ∵ a(b+c) = ab + ac
Therefore, the first step to solving the equation is:
[tex]3x+24 = 42[/tex]
Hence, 3x + 24 = 42 is the correct option.
