Question

ayuda con estas ecuaciones

(A) 2-3(r-7)-7r=4(r-2)+8

(B) 7-6(c-1)+ 3(3-4c)=7+(7c-4)

Answer 1

c(-264) =:-[24+314 =-
257

Answer 2

2 - 3 (r - 7) - 7r = 4 (r - 2) + 8

2 - 3r + 21 - 7r = 4r - 8 + 8

23 - 10r = 4r

- 10r - 4r = - 23

- 14r = - 23

r = -23/-14

r = 23/14
--------------------------------------

7 - 6 (c - 1) + 3 (3 - 4c) = 7 + (7c - 4)

7 - 6c + 6 + 9 - 12c = 7 + 7c - 4

22 - 18c = 3 + 7c

- 18c - 7c = 3 - 22

- 25c = - 19

c = -19/-25

c = 19/25
