Question

ATIVIDADE 2

a) 9x – 2 = 4x + 18 b) 2x – 10 + 7x + 10 = 180 c) 7y – 10 = y + 50

d) 4x – 18 + 3x = 10 e) 2x + 5 + x + 7 = 18 f) 5x – 91 = 4x – 77

g) 7x + 1 = 5x – 7 h) 4x + 5 = x + 20 i) 3(x + 1) + 2(2x – 3) = 5 (x – 1 ) + 8

j) 2(x + 5 ) – 4 = 26 k) 3(x + 3 ) – 5 = 22 l) 2(2x + 7 ) + 3(3x – 5 ) = 3(4x – 5 ) – 1

m) 3( x + 2 ) = 2 ( x – 7) n) 4(2x –1 ) = 3( x+2 ) o) 4(2m-1) + 3m = 2(4m-1) – (2 –m

p) 3(x + 3 ) - 1 = 2 q) 3(x + 2 ) – 1 = 2(x + 3) – 7 r) 3(x + 1 ) + 2 = 5 + 2(x - 1 )

s) 3(2x – 3 ) + x = 5 t)3x + 5 + 2x + 6= x + 27 u) 2 ( x – 1 ) + 3(x + 1 ) = 4(x + 2)

v)3(3x +8) -5x = x - 3 w) 5 (2x – 1 ) = 3 (x + 10) x) 2(x – 3 ) + 8x +4 = 5 (x + 2 )

Podem me falar o número certo para cada x por favor ​
