<span>solve -2(2x + 5) - 3 = -3(x - 1)
-4x - 10 -3 = -3x + 3
-4x - 13 = -3x + 3
Add 3x to both sides
-4x - 13 +3x = -3x +3
Simplify
-x - 13 = 3
Add 13 to both sides
-x - 13 + 13 = 3 + 13
Simplify
-x = 16
multiply both sides by (-1)
x = -16</span>
24 divided by 8 is 3

Answer:
We can write proportion as:

Step-by-step explanation:
A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours
Proportion:
A proportion is used when two ratios are equal. It can be written as a/b=c/d
In our case we have:
a= 30 miles
b = 1.5 hours
c = x miles
d = 4 hours
We can write proportion as:

Hello !
Okay so what you do is add 10 to the other side
2k - 10 +10 = 6 + 10
You would get ....
2k = 16
Next you divide 16 by 2 which is 8
and that means 8 is equal to k
K = 8
