Make x the subject of the formula
dx - t = 8

x = (8+t)/d

Step-by-step explanation:

Since you want to make x the subject of the formula, you would want it along. so you should move the t to the other side, which will get you dx = 8+t, then you will have to divide both sides by d to get the x along, and in this case, you will get x = (8+t)/d

firstly,u move (t) to the right side

dx=8+t

secondly,u divide both side by (d) the coefficient of x

dx=8+t

x=8+t÷d
