Answer 1

Vai dar trabalho digitar, mas vamos lá hausu :p

A) 3x + 5 =20
3x= 20-5
3x= 15
x= 15/3. x= 5

B) 4x +6 = 26
4x = 26 - 6
4x = 20
x = 20/4. x=5

C) 2x -12 = 4
2x = 4+12
x = 16/2. x=8

D) 3x+16= 40
3x = 40-16
3x = 24
x= 24/3. x=8

E) 2x +22 = 34
2x = 34-22
2x = 12
x= 12/2. x=6

F)5x +12= 22
5x = 22-12
5x= 10
x = 10/5. x=2

G) 3x - 11= 10
3x= 11+10
3x= 21
x= 21/3. x=7


H)'4x+18=30
4x = 30-18
4x = 28
x = 28/4. x=7


I)5x-13=12
5x = 13+12
5x = 25
X= 25/5. x =5


J)4x+3=35
4x= 35 -3
4x = 32
x= 32/4. x=8

K)3x-14=13
3x= 13+14
3x = 27
x=. 27/3. x=9

L)2x-14=20
2x = 20 +14
2x= 16
x= 16/2. x=8

M)2x-12=8
2x = 8+12
2x= 20
x= 20/2. x=10

N)3x+40=52
3x= 52 -40
3x= 12
x= 12/3. x=4

O)4x -12=24
4x = 24+12
4x= 36
x= 36/4. x=9

P)5x+ 15=35
5x = 35 -15
5x = 20
x= 20/5. x=4


Q)3x - 14=4
3x= 14+4
3x= 18
x= 18/3. x =6
