Question

14. Resolva as equações a seguir:
a) x + 5 = 12
b) y = 9=3
c) t- 12 = 15
d) y +5=-4
e) 2p = 8
f) 3z + 4 = 22
g) 5x +4 -2x = 26 - 3x
h) 3t - 4 = 11
1) 4x +9= 3x+5
j) 5+3 - 34 = -24 +19
​

Answer 1

a)

x = 12 -5

x = 7

b)

y = 3 +9

y = 12

c)

t = 15 +12

t = 27

d)

y = -4 -5

y = -9

e)

p = 8/2

p = 4

f)

3z = 22 -4

z = 6

g)

3x +3x = 26 -4

x = 22/6 = 11/3

h)

3t = 11 +4

t = 15/3 = 5

i)

4x -3x = 5 -9

x = -4

j)

8 -34 = -24 +19

-26 ≠ -5
