Question

1) resolva as seguintes equações

a)5x+3=33

b)25x+4=10x+19

c)4x+5=2x+25

d)2.(x+15)=35

e)3.(x+3)=12

x/2=6/3

f)2x/4=1/2

Answer 1

$5 \times = 33 - 3 = \\ 30 \div 5 \times = 6 \times$
$25 \times - 10 \times = 15 \times \\ 19 - 4 = 5 \\ 15 \times \div 5 = 3$
$4 \times - 2 \times = 2 \times \\25 - 5 = 20 \\ 20 \div 2 \times = \\ 10 \times$
