Question

Which number line shows the solution set for |10-5y|=20

Answer 1

answer is Y=6

Explanation:

edge2020

Answer 2

y = -2 and y= 6

Explanation:

Step 1:-

Given solution is |10-5 y|=20

we know that modulus |x| = 1

we will take values x= -1 and x=1 so we will apply like this on above given problem is
`10-5 y= 20`

on simplification, we get
`10-20 =5 y`

`-10 = 5 y`

`y=-2`

Step 2:-

and
`10-5 y= - 20`

on simplification, we get
`10+20 =5 y`

`30 = 5 y`

dividing with 5 , we get

`y=6`

Final answer:-

The solution is

`y=-2`

`y=6`
