Question

me ajudemmm pfvrr a)2(x-3)=-5(x+4). b) 2(3y-1)-16=8y​

Answer 1

a) 2x-6= -5x -20

5x+2x= 6 -20

7x= -14

x= -2

b) 6y-2 -16= 8y

-8y+6y= 16+2

-2y=18

y= 18÷(-2)

y= -9

Answer 2

Resposta:

a)

2(x-3)= -5(x+4)

2x-6=-5x-20

2x+5x=-20+6

7x= - 14

x= -14/7

x= -2

b)2(3−1)−16=8

6−2−16=8
