Question

Resolva as seguintes equações:
a) 5x + 3 = 38 b) 5x + 3 – 3 = 38 c) 5x = 35 d) 8x – 11 = 4x + 13 e) 4x – 11 = 13
f) 4x = 24 g) 9x  8  8 37  8 h) 8x = 30 – 2x h) 11x = 77 i) − 39 = −79
j)10 = + 8 k)15 = + 20 l) 3(x + 3 ) – 5 = 22 m) 2(2x + 7 ) + 3(3x – 5 ) = 3(4x – 5 ) – 1
n) 3( x + 2 ) = 2 ( x – 7) o) 4(2x –1 ) = 3( x+2 ) p) 4(2m-1) + 3m = 2(4m-1) – (2 –m)
