x = 4

Step-by-step explanation:

I don't know what you mean by sketch pad but here is the working out

4x + 4 = 20

-4            -4

4x = 16

÷4           ÷4

x = 4

Hope this helps :)

How to find the other endpoint of a line when only given the first endpoint and the midpoint?
Schach [20]
If we have a line, and the endpoints are(x₁,y₁) and (x₂,y₂), the midpoint will be:( (x₁+x₂)/2 , (y₁+y₂)/2 );

Data:
Endpoint₁: (2,-3)
Midpoint: (6,6)

Therefore:

(2+x₂)/2=6
2+x₂=12
x₂=12-2
x₂=10

(-3+y₂)/2=6
-3+y₂=12
y₂=12+3
y₂=15

Answer; the other endpoint of a line will be (10,15)

Simplify x+ 5/8=6 for an answer
marshall27 [118]
If it is : (x + 5) / 8 = 6
multiply both sides by 8, eliminating the 8 on the left side
x + 5 = 8 * 6
x + 5 = 48
x = 48 - 5
x = 43

if it is : x + (5/8) = 6
subtract 5/8 from both sides
x = 6 - 5/8
x = 48/8 - 5/8
x = 43/8 or 5 3/8
