Question

podem me ajudar 2) Resolva as seguintes equações a) 2x + 5 - 5x = -1 b) 5 + 6x = 5x + 2 c) x + 2x - 1 - 3 = x d) -3x + 10 = 2x + 8 +1 e) 5x - 5 + x = 9 + x f) 7x - 4 - x = -7x + 8 - 3x g) -x -5 + 4x = -7x + 6x + 15 h) 3x - 2x = 3x + 2 i) 2 - 4x = 32 - 18x + 12 j) 2x - 1 = -3 + x + 4 l) 3x - 2 - 2x - 3 = 0 m) 10 - 9x + 2x = 2 - 3x n) 4x - 4 - 5x = -6 + 90 o) 2 - 3x = -2x + 12 - 3x

Resposta:

Explicação passo-a-passo:

$A)-3x=-5-->x=\frac{5}{3}\\B)x=-3\\C)2x=4-->x=2\\D)-5x=-1-->x=\frac{1}{5}\\E)6x=14-->x=\frac{7}{3} \\F)16x=12-->x=\frac{3}{4} \\G)10x=20-->x=2\\H)-2x=2-->x=-1\\I)14x=42-->x=3\\J)x=2\\L)x=5\\M)-4x=-8-->x=2\\N)-x=-88-->x=88\\O)2x=10-->x=5$
