Answer 1

2x+4./7=5/3
42x+12=35   42x=35-12=23  x=23/42

1,2xX-7=5
12/10xX-7=5
12X/10-7=5   12X-70=50  12X=50+70  12X=120   X=10

3X-4/9=7   27X-4=63   27X=63+4   27X=67  X=67/27
D. 4/11X=8/33     4x33=11Xx8    132=88x   x=132/88=33/22=3/2
E.3/5-x-4/9=1/3     27-45x-20=15    -45x=15-7   -45x=8  x=-8/45
