Question

-2/3+y=-6/7

Answer 1

there are two ways to do this....with fractions or without fractions...

with fractions...
-2/3 + y = -6/7 (add 2/3 to each side)
y = -6/7 + 2/3 (common denominator is 21)
y = - 18/21 + 14/21
y = - 4/21

without fractions...
-2/3 + y = -6/7 (to get rid of fractions multiply the equation by the LCD which is 21)
-14 + 21y = -18 (add 14 to both sides)
21y = -18 + 14
21y = -4 (divide by 21)
y = -4/21

either way will get you the same answer
