ECUACIONES LINEALES

1) 4x+3=2x+5

2) 3x+1=x+5

3)x+10=5x+2

4) 3(x+4)=-5x-36

5) 5(r+6)=-5(r-4)

Answer 1

1) 4x+3=2x+5 
    2x = 2
    x = 1 
2) 3x+1=x+5
  2x = 4
  x =2
3)x+10=5x+2
  8 = 4x
  x= 2 
4) 3(x+4)=-5x-36
   3x + 12 = -5x -36 
   2x = - 48
   x= -24
5) 5(r+6)=-5(r-4)
   5r + 30r = -5r +20 
   10r = -10
   r = -1

Answer 2

4x-2x= 5-3
2x=2
x= 2/2
x= 1

3x-x=5-1
2x=4
x= 4/2
x= 2

x-5x= 2-10
-4x= -8
x= -8/-4
x= 2

3x+12=5x-36
3x-5x= -36-12
-2x= -48
x= -48/ -2
x= 24

5r+30=-5r+20
5r+5r= 20 -30
10r= -10
r= -10/ 10
r= -1
