Answer 1

Your answers all seem correct.

Answer 2

`7=x`

Explanation:

Equation

`4x = 7(x - 3)`

we apply distributive property
`c(b+a)= bc+ac`

`4x = 7x - 21`

Group similar terms

`21=7x-4x`

Resolve addition / subtraction operations

`21=3x`

clear the x. Dividing both terms by the coefficient that accompanies the x

`(21)/(3)=(3x)/(3)`

`7=x`
