Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
7*x-4-(21)=0
Solve : 7x-25 = 0
Add 25 to both sides of the equation :
7x = 25
Divide both sides of the equation by 7:
x = 25/7 = 3.571
Answer:
35
Step-by-step explanation:
1. 5/7x - 4 = 21
2. Add 4 on both sides --> 5/7x = 25
3. Divide by 5/7 on each side
4. on the left it cancels out and you are left with ---> x = 35
