Question

Ecuaciones lineales
2r=6
2r-3=6+r
2(2r-3)=6+r
2(r+1)-3(r-2)=r+6

Answer 1

Explicación paso a paso:

2r=6

r=6/2

r=3

2r-3=6+r

2r-r=6+3

r=9

2(2r-3)=6+r

4r-6=6+r

4r-r=6+6

3r=12

r=4

2(r+1)-3(r-2)=r+6

2r+2-3r-6=r+6

2-6-6=-2r+3r+r

-10=2r

r= - 5

Answer 2

Respuesta:

Hola!

Explicación paso a paso:

*2r = 6                      

r = 6 ÷ 2

r = 3

*2r - 3 = 6 + r

2r - r = 6 +3

r = 9

*2(2r-3) = 6 + r

4r - 6 = 6 + r

4r - r = 6 + 6

3r = 12

r = 12 ÷ 3

r = 4

*2(r+1) - 3(r-2) = r + 6

2r + 2 - 3r + 6 = r + 6

- r + 8 = r + 6

- r - r = 6 - 8

-2r = -2

r = -2 ÷ -2

r = 1

Espero te sirva :)✨
