SOS if anyone could help that would be appreciated!!!❤️

Answer 1

See below

Explanation:

`2e)15-4x=10x+45`

Solve:

`15-4x=10x+45\\-4x-10x=45-15\\-14x=30\\ \boxed {x=-(15)/(7)}`
`3(x+1)=21`

Check:

`15-4 \left(-(15)/(7) \right)=10\left(-(15)/(7) \right)+45`

`15+(60)/(7) \right)=-(150)/(7) +45`

`(210)/(7) =30`

`30=30`

`3a) 3(x+1)=21`

Solve:

`3(x+1)=21\\3x+3=21\\3x=18\\x=6`

`3b) 2+3(x+1)=6x`

`2+3x+3=6x\\5=3x\\`

`x=(5)/(3)`

`3c) -2(2x-3)=-2`

Solve:

`-2(2x-3)=-2\\-4x+6=-2\\-4x=-8\\x=2`
