Question

RESOLVA AS EQUAÇÕES:

5 X - 3 = 2 X - 9

4 X - 8 = 2 X + 6

Y - 1 = - 8

X + 9 = 18

2 X + 1 = X + 5


me ajudem pfvr

Answer 1

Resposta:

1) 5x-3=2x-9 -> 5x-2x=3-9 -> 3x=-6 R- x= -2

2) 4X-8=2X+6 -> 4X-2X=8+6 -> 2X=14 R- x= 7

3) y-1=-8 -> y=1-8 R- y= -7

4) x+9=18 -> x=18-9 R- x=9

5) 2x+1=x+5 -> 2x-x=5-1 -> R- x=4
