Question

Me ajudem nessas equacoes
A) 5x-9=-8
B) 9x-2=11
C) 8x+5=-3
D) 3x+15=16
E) 2x+5=8

Answer 1

a) 5x - 9 = - 8
5x = - 8 +9
5x = 1
x = 1/5

b) 9x - 2 = 11
9x = 11 + 2
9x = 13
x = 13/9

c) 8x + 5 = - 3
8x = - 3 - 5
8x = - 8
x = - 8/8
x = - 1

d) 3x + 15 = 16
3x = 16 - 15
3x = 1
x = 1/3

e) 2x + 5 = 8
2x = 8 - 5
2x = 3
x = 3/2

Answer 2

A)5x-9=-8
5x=-8+9
5x=1
x=1/5

B)9x-2=11
9x=11+2
x=13/9

C)8x+5=-3
8x=-3-5
x=-8/8

D)3x+15=16
3x=16-15
x=1/3
E)2x+5=8
2x=8-5
2x=3
x=3/2
