Question

B. 3x =7x -5 +2

C. 2y -x -1 +3y +2x +1

D.4a +6b/5 -2 +3b/10 +a/3 -1 -b

E.2a -7 +3a +4 -5a +1 -11a

F. 2a -3b +c -4a +2b -5c -3a -b +c

G.3x +2y -1 +7x -5y +3 -2x +y +6

Answer 1

 B. 3x =7x -5 +2  ==> 7x - 3x = 5-2 ==> 4x = 3 ==>x = 3/4

C. 2y -x -1 +3y +2x +1==> x + 5y

D.4a +6b/5 -2 +3b/10 +a/3 -1 -b
     4a +a + 6b+ 3b -b -2-1
             3     5     10
      12a+a +  12b+3b-10b - 3
           3                  10
          13a + 5b - 3
             3     10

E.2a -7 +3a +4 -5a +1 -11a ==> 2a+3a-5a-11a-7+4+1==> - 11a - 2

F. 2a -3b +c -4a +2b -5c -3a -b +c ==> 2a-4a-3a-3b+2b-b+c-5c+c==> - 5a - 2b - 3c

G.3x +2y -1 +7x -5y +3 -2x +y +6 ==>3x+7x-2x+2y-5y+y-1+3+6==>8x - 2y + 8
