Combine like terms to simplify the expression below:
14x - (2x -y) -y STEP BY STEP PLEASE
2 answers:
14x - (2x - y) - y
14x + (-1(2x - y)) - y
14x + (-1(2x) - 1(-y)) - y
14x + (-2x + y) - y
14x + 1(-2x + y) - y
14x + 1(-2x) + 1(y) - y
14x - 2x + y - y
14x - 2x
12x
14x-(2x-y)-y
First you must distribute through the negative in front of the parenthesis means the same as
14x- 1(2x-y)-y
so you must multiply 2x and -y by -1
-1* 2x= -2x
-1* -y= y ( two negatives equal a positive)
Now: 14x-2x+y-y (the y's cancel leaving-)
14x-2x
You're answer is 12x

Hi
85% ⇒ 68
100% ⇒ x
85x = 100·(68)
