Question

PRECISO DE AJUDA URGENTEMENTE!!!!!
Resolva as seguintes equações:
a) 7(x - 5) = 3 (x + 1)
b) 3 ( x - 2 ) = 4 (-x + 3)
c) 2 (x +1) - (x -1) = 0
d) 5(x + 1) -3 (x +2) = 0
e) 13 + 4(2x -1) = 5 (x +2)
f) 4(x + 5) + 3 (x +5)= 21
g) 2 (x +5 ) - 3 (5 - x) =10
h) 8 ( x -1) = 8 -4(2x - 3)

Answer 1

Resposta:

a)7(x - 5) = 3 (x + 1)

7x-35 = 3 (x + 1)

7x-35 = 3x + 3

7x-3x - 35 = 3

7x-3x = 3 + 35

4x = 3 + 35

4x = 38

$x = \frac{19}{2}$
