Which is a solution to the equation |10-5y|=20

y=2

y=4

y=6

y=10

Answer:

y=6

Step-by-step explanation:

|10-5y|=20

Since the absolute value is isolated, we can then separate the equations

For absolute values, there is a positive and negative when we remove the absolute values.

10-5y = 20 10-5y= -20

Subtract 10 from each side

10-10-5y = 20-10 10-10-5y= -20-10

-5y = 10 -5y = -30

Divide by -5

-5y/-5 =10/-5 -5y = -30/-5

y =-2 y =6

- ( x - 1 ) = -4x - 2

Answer:

x=-1

Step-by-step explanation:

1. Remove the parenthesis

-x + 1 = -4x - 2

2. Get x alone

-x + 1 = -4x - 2

+1x +1x

1=-3x - 2

+2 +2

3=-3x -3x/-3= x 3/-3 = -1

x=-1
