Answer:
x = 3
Step-by-step explanation:
The goal of solving this equation is finding the value of the variable, "x". To do that, we need to get x alone on one side of the equation.
Our first step is to Combine Like Terms.
[tex](7+5)(x-2)=12\\\\12(x-2)=12[/tex]
Next, Divide 12 from both sides of the equation.
[tex]12(x-2)=12\\\\\frac{12(x-2)}{12}=\frac{12}{12}\\\\x-2=1[/tex]
Finally, Add 2 to both sides of the equation.
[tex]x-2=1\\\\x-2+(2)=1+(2)\\\\x=3[/tex]
So, x is equal to 3.
