Answer:
x=3
Step-by-step explanation:
<span>See examples before for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2. my own words didnt get off google im a teacher</span>
The second one it's double.
d = b - 3 / 10
Step-by-step explanation:
b = 10d + 3
- Place +3 in the other side of the equal sign
- + 3 becomes - 3
- b - 3 = 10
- Divide both sides by 10 to make d the subject
- b - 3 / 10 = 10d / 10
- d = b - 3 / 10
