Question

Qual é a resposta das equações??

A) 2X+6=X+8 B)3X+1=X+8 C)2X+1=5



D) 3X+3=X+4 E) 3X+6=2X+12 F) 4X+5=3X+15

Answer 1

A- 2x-x=8-6/ x=2
B- 3x-x=8-1/ 2x=7/ x=3,5
C- 2x=5-1/ 2x=4/ x=2
D- 3x-x=4-3/ 2x=1/ x=0,5
E- 3x-2x=12-6/ x=6
F- 4x-3x=15-5/ x=10

Answer 2

a)2x-x = 8-6
X= 2

b) 3x-x= 8-1
2x= 7
X = 7/2
X= 3,5

c) 2X = 5-1
2x= 4
X = 4/2
X= 2

d)3x-x= 4-3
2x=1
x= 1\2
x= 0.5

e)3x-2x = 12-6
x = 6

f)4x+5= 3x+15
4x-3x = 15-5
x= 10
