Question

resolver as equações

parte 1

a)x+5=8

e)x +9= -1

i)4 = x 10

m)3x = 15

j)7 = x + 8

n)2x = 10

q)3x - 13 = 8

u)2x = 14

r)4x-9 = 23

v)7x = -21

c)x+6=5

g)10 = x+8

k)x1=5

0)3x = -9

d)x - 7=-7

h)15 = x + 20

1)2x + 4 = 16

p)2x2= 12- 5x

s)7x-33-12

w)4x = -12

t)33+ x = 5 - 3x

x)35x = -105

parte 2

a) 9x 2 = 4x + 18

d) 4x 18+ 3x = 10

b) 2x10 + 7x + 10 = 180

e) 2x + 5 + x + 7 = 18

c) 7y-10= y + 50

g) 7x+1=5x-7

h) 4x + 5 = x + 20

f) 5x-91-4x - 77

i) 2(x+5)-4=26

k) 3(x+3)-5=22

m) 3(x+2) = 2 (x-7)

b)x 4 = 3

f)x-39-79

n) 4(2x-1)=3(x+2)

p) 3(x+3)-1=2 q) 3(x+2)-1 =

i) 3(x+1)+2(2x-3)=5 (x-1)+8

1) 2(2x + 7) + 3(3x-5)=3(4x-5)-1

o) 4(2m-1) + 3m=2(4m-1)-(2-m)

s) 3(2x-3) + x = 5

v)3(3x +8) -5x = x - 3

1)3x +5+2x+6=x+27

2(x+3)-7|r) 3(x+1)+2=5+ 2(x - 1)

u) 2(x-1)+3(x + 1) = 4(x + 2)

w) 5 (2x-1)=3(x+10)

x) 2(x-3) + 8x +4= 5 (x+2)​
