Answer 1

Answer:

i guess it's correct

Step-by-step explanation:

10x -8x +2+10

= 10x-8x+12 =0

= -2x = -12

= X=12/2

= X = 6

Answer 2

$\:$

1) 10x - 8x + 2 + 10

= x ( 10 - 8 ) + 12

= x (2) + 12

= 2x + 12

= 2( x + 6 )

$\fbox{ \pink{10x - 8x + 2 + 10} = \color{purple}{2(x + 6)}}$

2) 3a + 7 + 2 ( 3 + a )

= 3a + 7 + 2(3) +2(a)

= 3a + 7 + 6 + 2a

= 3a + 2a + 7 + 6

= a( 3 + 2) + 13

= a (5) + 13

= 5a + 13

$\fbox{ {\color{red}3a + 7 + 2(3 + a)} = \color{blue}5a + 13}$
