Xy - 5 = k (move the known term to the right with changed sign)

xy = k + 5

Now we have x multiplied for y...to delete the y, divide both terms for y.

xy/y = (k+5)/y

x = (k+5)/y

3y + 5x = 7

Move 3y to the right with changed sign (this to make x the variable for which we solve the equation)

5x = 7 - 3y

Divide every term for 5

5x/5 = 7/5 - 3y/5

x = 7/5 - 3y/5

m/n = p-6

Multiply both terms for n, since we should delete the fraction m/n

m = pn-6n

Factor...

m = n(p-6)

to find n, move m to the right with changed sign.

Divide both for p-6

m/p-6 = n

n = m/p-6

F = 9c/5 + 32

9c/5 + 32 = F

Move 9c/5 to the left (don't change sign) to make it the default variable. And move all the rest to the right but changing sign.

9c/5 = f - 32

To delete the fraction, multiply every term for 5

9c = 5(f) + 32(5)

9c = 5f - 160

Divide both for 9

c = 5f/9 - 160/9

Two trains leave stations 360 miles apart at the same time and travel toward each other. One train travels at 70 miles per hour
cricket20 [7]
S=d/t     ⇒d=s*t
s=speed
d=distance
t=time

The first train :
d=x

x=70 miles/h*t                             ⇒   x=70t  (1)

The second train
d=360 miles - x

360 miles - x=80 miles/h*t          ⇒360-x=80t   ⇒ x=360-80t   (2)

therefore, with the equations (1) and (2) we have a systeme of equations:

x=70t
x=360-80t

we can solve this system of equations by equalization method.

70t=360-80t
70t+80t=360
150t=360
t=360/150=2.4     (≈2 hour  24 minutes)

Answer:  the first train meet with the second train in 2 hour 24 minutes.

Olegator [25]
To estimate, round 3102 to 3100
round 1-10 to 2500
1-70 to 2100 
1-80 to 2900
2900+2100+2500+3100=10600mi
Yes it is reasonable because you add and subtract numbers when estimating, however it is not exact
