Question

1. Resolva as equações a seguir, considerando U= Q.
a) 2x - 7 = -5x + 1
b) 4x + 13 = 43 - X
c) 2x - 3 = 1 - (3 - 3x)
d)×+2/3-2×-1/2=×+3
e) -3(x - 1) + 4 = ×/2-2
f) 3(x + 6) - (-x + 1) = 5x +8
g) 4×/5-×=-5
h) 5x - (-2x + 3) = 3x + 7​

Answer 1

Resposta:

a) 2x - 7 = -5x + 1

2x + 5x = 1 + 7

7x = 7

x = 1

b) 4x + 13 = 43 - x

4x + x = 43 - 13

3x = 30

x = 10
