Multiply you first equation by 2 to get 4x + 10y = 22
Now the x terms can be eliminated and cancelled out using elimination.
4x + 10y = 22
4x + 3y = 1

To eliminate you need to "subtract", so you need to multiply one of the equations by -1. 

4x + 10y = 22
-4x -3y = -1
------------------
0 + 7y = 21
y = 3

Now plug 3 into either one of the equations to get x.

Pls help 10 pnt <br> X=<br> 6<br> 3.75<br> 2
kolezko [41]

4 × ( x + 4 ) = 3 × ( 3 + 5 )

4 × ( x + 4 ) = 3 × 8

Divide both sides by 4

x + 4 = 3 × 2

x + 4 = 6

Subtract both sides 4

x = 2

 For this case what you should do is find the area of the triangle which will be given by:
 A = (1/2) * (b) * (h)
 Where
 b: base
 h: height
 Substituting the values we have:
 A = (1/2) * (25 1/2) * (15)
 A = 191.25 feet ^ 2
 Answer:
 she will need 191.25 feet ^ 2 to cover the back of the cabin
