Answer:
x = 17/2 = 8.500
Step-by-step explanation:
Equation at the end of step 1 :
2 • (x - 5) - 7 = 0
Step 2 :
Equation at the end of step 2 :
2x - 17 = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve : 2x-17 = 0
Add 17 to both sides of the equation :
2x = 17
Divide both sides of the equation by 2:
x = 17/2 = 8.500
