Question

gente me ajudeeeee

resolva as equações:
a) 2 (x-7)+=32
b) 3.(x+12)-48=72
c) 4.(x+7)-63=76
d) 2.(x+3)+12=5(x-3)
e) 4.(2x+8)=8(x-4)
f) x+9=2(x-3)
g) x+4=14

Answer 1

a)2x -14 =32
2x= 32 +14
x= 46/2
x= 23

b)3x +36 -48 = 72
3x = 72-36+48
3x= 84
x= 84/3
x=28

c)4x+28-63=76
4x =76 -28+63
4x=111
x=27.75

d)2x+6+12=5x-15
2x-5x = -15-6-12
-3x = -33
x = 11

e)8x+32=8x-32
8x-8x = -32 -32
nao da...

f)x+9=2x-6
-x = -6-9
x = 15

g)x+4=14
x= 14-4
x= 10
