Since this line is one single line you want to add the two parts rather than multiply.

(x - 7) + (x - 3) = 12

x - 7 + x - 3 = 12

Next you want to simplify everything so add the values with the variables together and add the constants together

2x - 10 = 12

Get the term with the variable on one side

2x = 22

Divide by 2 on both sides to find x

x = 11
