Question

2) Resolva as equações a seguir: a)3X – 22 = x +4
b) 5X + 5 = 35
C) 4x = 36
d) x - 8 = - 20
e) x + 12 = -33
f) 26x = -26
g) 4 – X = -4
h) -3x = 27
i) 3x = 9
j) 3x + 10 = 2x – 20
L) -2x + 30 = -5x + 60​

Answer 1

Explicação passo-a-passo:

a) 3x - x = 4 +22

2x = 26

x= 26/2

x= 13

b) 5x = 35-5

5x = 30

x= 30/5

x= 6

d) x = -20 +8

x= - 12

e) x = -33 -12

x= - 45

f) x = -26/26

x= - 1

g) 4+4= x

x= 8

h) x= 27/-3

x= -9

i) x = 9/3

x= 3

j) 3x -2x = -20-10

x = -30

l) -2x +5x = 60-30

3x = 30

x= 30/3

x= 10
