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:
exact form: 9988/23
decimal form: 434.26
mixed number form: 434 6/23
Step-by-step explanation:
m is 48 because since they said perimeter you would have to add 3 twice and then subtract is with 102 which is 96 the divide 96 by 2 and you would get 48.
