8. The sum of two numbers is 8 less than twice the first number. Their difference is 4 less than twice
Delicious77 [7]

Answer:

14 and 6

Step-by-step explanation:

Let's start by naming the first number x.

We can name the second number y.

We can set up equations to model our situation.

x+y=2x-8

x-y=2y-4

Let's simplify the equations.

x+y=2x-8

Subtract 2x from both sides

-x+y=-8

__________

x-y=2y-4

Subtract 2y from both sides.

x-3y=-4

Add the two equations together to eliminate x.

x-3y=-4

-x+y=-8

________

0x-2y=-12

-2y=-12

Divide both sides by -2.

y=6

The second number is 6.

Plug that back in.

x+6=2x-8

Subtract x from both sides

6=x-8

Add 8 to both sides

x=14

The first number is 14

-1/2x+3=-4x+7
borishaifa [10]
Like a first step bc. there is a denominator this will be more usefully eliminate it so what you can make it multiplied both sides by 2 
- so will get 

-2/2x +2*3/2 = 2(-4x+7)/2

(-2x +6)/2 = 2(-4x+7)/2   common denominator the 2 so make the numerators equal and solve for x 

-2x+6=-8x+14

6x=8

hope helped
