What is the solution of 3(x-1)=2x+5
Tpy6a [65]
3( x - 1 ) = 2 x + 5
 
Expand 3(x-1) :

3*x - 3 x 1 

3 x - 3 = 2 x + 5

Add 3 both sides :

3 x - 3 + 3 = 2 x + 5 + 3

3 x = 2 x + 8

3x - 2 x = 8

x = 8

hope this helps!

PLEASE HURRY THIS IS DUE IN 20MIN
OverLord2011 [107]

This is not my answer I found it from another brainly

From the beginning we know we are dealing with two different rates. Distance is equal to (Speed X Time). We have two different speeds though. We will call the min speed = x and the max speed = y. With those two ideas in place we can make two equations for both Tony and Rae.

Tony:

2x+3.5y=355

Rae:

2x+3y=320

Now you can solve the equations by subtracting Rae's equation from Tony's

.5y=35 solve for y and you get 70

Now plug that y value back into either equation and you can solve for x. I'll use Rae's distance:

2x+3(70)=320

x=55
