resolva as seguintes equacoes do 1 grau
a) 6+4×+4=24+2×
B) 8+4×-6=×+13
C)3+×-25= - ×+8
D)2×- 6+2×= 3× - 17
I) 7 - 2× - 4 = 3× + 16​

Answer 1

Resposta:

a) 6+4x +4= 24+2x

4x-2x =24-4-6

2x= 14

X= 14/2

X= 7

b) 8+4x-6=x+13

4x-x= 13+6-8

3x= 11

X = 11/3

c) 3+x-25= -x+8

X+x= 8+25-3

2x= 30

X= 30/2

X= 15

d)2x-6+2x=3x -17

2x+2x-3x= -17+6

X= -11

e) 7-2x -4= 3x+16

-2x-3x= 16+4-7

-5x= 13

X=13/5
