Hola por favor ayuden

Answer 1

a)( x − 3 ) = ( 2 − x − 2 /3 ) ⋅ ( 2 )

( x − 3 ) = − 2 ( x − 8 ) /3

x − 3 = − 2( x − 8 ) /3

5 ( x − 5 )/ 3 = 0

5 ( x -5 ) = 0

5 x − 25 = 0

5 x = 25

x = 5

b) x²+8x+15+(−x²−2x)=5x

x²+8x+15−x²−2x=5x

8x+15+0−2x=5x

8x+15−2x=5x

6x+15=5x

6x+15−5x=0

x+15=0

x=−15

d)x/8=15/4

(x)⋅(4)=(8)⋅(15)

4x=(8)⋅(15)

4x=120

x=30
