Question

Resolva as seguintes equações do 1-Grau com uma variável


a) 7x-4= 5x+6
b) 10+3x= 2x+9
c) 5x+2-x+8=0
d) 5x-13=7x-19
e) 2x+7-x=3-4x
f) 11-x+5= 4x+22-6x
g) x+3+2x-5x+x-11=0
h) x+12+x= 12-x

Answer 1

a) 7x-5x = 6+4
2x = 10
x = 5

b)
3x-2x= 9-10

x = -1

c) 4x = -10
x = -10/4

x = -5/2

d) 2x = 6
x = 3

e) 5x = -4
x = -4/5

f) x = 6

g) x = -8

h) x = 0
