Answer:
hi if you want to solve fore x and y there must be 2 equations .
Step-by-step explanation:
so that you could solve them simultaneously
-7x + 2y = 4
here 2y - 4 = 7x
( 2y -4)/7 = x
Answer:
-2b/(a-b)
Step-by-step explanation:
1− (a+b/a−b)
We need to get a common denominator of a-b
1 = (a-b)/(a-b)
Replace 1 with (a-b)/(a-b)
(a-b)/(a-b) - (a+b)/(a-b)
Put over the common denominator
(a-b) - (a+b)
-----------------
(a-b)
Distribute the minus sign.
(a-b) - a-b)
-----------------
(a-b)
a-a-b-b
---------------
a-b
-2b
----------
a-b
