Answer:
The answer to your question is: 32 x + 2y - 107
Step-by-step explanation:
Simplify 5+2{y-4[3x+7(2-x)]}
5 + 2 { y - 4[ 3x + 14 - 7x ]}
5 + 2 { y - 12x -56 +28x }
5 + 2y - 24 x - 112 + 56x like terms
32 x + 2y - 107

Answer:
631139.04 kilometers in 3 years
Step-by-step explanation:
Let x = how many kilometers she walk
y = time (minutes)
Since she walks 4km in 10 minutes.
x = 4, y = 10
(4,10)
But how many minutes if she walk only a kilometer? Divide x and y by 4.
(1,2.5)
She walks a kilometer under 2.5 minutes.
Now finding rate of changes.

Since m = 2.5
and of course, the function should be proportional so the equation should be y = mx.

Since time should be minutes instead of years.
Since 3 years = 1577847.6 minutes

Divide both sides by 2.5

Answer:
This question is not complete. Can you add the rest?
The equation would be 5+4x=7x+11
Which comes out to:
x = - 2
