Question

Drag each equation to show if it could be a correct first step to solving the equation

3(x+8)=42.

Answer 1

(3 x
`x`) + (3 x 8) = 42

Explanation:

3(x+8) = 42

3*x + 3*8 = 42

3x + 24 = 42

3x = 42 -24

3x = 18

x = 18 / 3

x = 6

Hope this helps :)

Answer 2

`3(x+8) = 42\\=>(x+8) = 14`

`3(x+8)=126\\=>x+8 = 42`

`3(x+8) = 42\\=> 3x +24 = 42`

`3(x+8) = 42\\=> 3\cdot x +3\cdot 8 = 42`

YES

`x +8 = 14\\3\cdot x +3\cdot 8 = 42\\3x + 24 =42`

NO

`3(x+8) = 126\\x+24 = 42\\3x+8 =42`
