Answer:
x = 10
Step-by-step explanation:
We need to isolate X.
3x - 7 = x + 13
subtract 13
3x - 7 - 13 = x
combine like terms
3x - 20 = x
subtract 3x
- 20 = x - 3x
Combine like terms
- 20 = - 2x
Divide by -2
10 = x
1) 4(x+7)=80
Value of x
Multiply
4x+28=80
4x=80-28
4x=52
X=52/4
X=13

where r is the radius of a circle.
