Answer: [tex]x=4[/tex]
Step-by-step explanation:
You need to find the value of the variable "x".
To solve for "x", the first step is to apply the Subtraction property of equality, which states that:
[tex]If\ a=b\ then\ a-c=b-c[/tex]
Then, you need to subtract 4 from both sides of the equation:
[tex]3x + 4 = 16\\3x + 4-4 = 16-4\\3x=12[/tex]
And finally, you can apply the Division property of equality, which states that:
[tex]If\ a=b\ then\ \frac{a}{c}=\frac{b}{c}[/tex]
Then you can divide both sides of the equation by 3, getting:
[tex]\frac{3x}{3}=\frac{12}{3}\\\\x=4[/tex]
