Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

4(x−7)=2(x+3)

Simplify both sides of the equation.

4(x−7)=2(x+3)

4x+−28=2x+6

4x−28=2x+6

Subtract 2x from both sides.

4x−28−2x=2x+6−2x

x−28=6

Add 28 to both sides.

2x−28+28=6+28

2x=34

Divide both sides by 2.

2x/2  =  34/2

x = 17

Two trains leave stations 306 miles apart at the same time traveling toward each other one is traveling at 90 mph the other at 8
Sergeu [11.5K]

Answer:

They will meet in 1.8 hours.

Step-by-step explanation:

Given that, distance between trains = 306 miles

Let they take time 't' to meet each other.

Speed of first train = 90 mph

Speed of second train = 80 mph

Let distance traveled by first train = D_1 miles

Formula for distance:

Distance = Speed \times Time

Distance traveled by first train, D_1 = 90t

Let distance traveled by first train = D_2 miles

Formula for distance:

Distance = Speed \times Time

Distance traveled by first train, D_2 = 80t

Total distance traveled is 306 miles.

i.e.

D_1+D_2=306\\\Rightarrow 90t +80t=306\\\Rightarrow 170t=306\\\Rightarrow t =\dfrac{306}{170}\\\Rightarrow \bold{t=1.8\ hr}

They will meet in 1.8 hours.
