y + (y+1) + (y+2) = -21

combine like terms

3y +3 = -21

subtract 3 from each side

3y = -24

divide by 3

y = -8

y+1 = -7

y+2 = -6

Answer: -8, -7, -6

G) X-3 (x - 2) = 3 (2-x)

Paraphin [41]

x - 3( x - 2 ) = 3 ( 2 - x )

Multiply 3 with x - 2 on LHS and 3 with 2 - x on RHS

or, x - 3x + 6 = 6 - 3x

Now take -3x to LHS and change its symbol to +. And take 6 to RHS and change it to negative.

or, x - 3x + 3x = 6 - 6

-3x and 3x will cancel out and also 6 and -6 will also get cancelled out.

or, x = 0

Answer:

x = 0

Hope you could understand.
