Question

I need help with a, b, c, and d.

Work shown

Answer 1

a.


`3x + 4 = x +8`

`3x - x = 8 - 4`

`2x=4`

`x= (4)/(2)`

`x=2`

b.


`4-2y = y +10`

`-2y-y = 10 - 4`

`-3y = 6`

`y=(6)/(-3)`

`y = -2`

c.


`5x+4-2x=-(x+8)`

`3x + 4 = -x-8`

`3x+x = -8-4`

`4x = -12`

`x= (-12)/(4)`

`x=-3`

d.


`-2-3k-2 = -2k + 8 - k`

`-3k - 4 = - 3k + 8`

`-4=8`

Impossible, we can't solve this equation.

Hope this helps !
