Question

ma ajuta cineva la 2? Dau coroana!!

Answer 1

a)3y+3x=3(y+x) b)3a+3b=3(a+b) c)3c-3d=3(c-d) g)3v+3=3(v+1) h)3+3p=3(1+p) i)6a+9b=3(2a+3b) m)15-12b=3(5-4b) n)30a-3=3(10a-1) o)36c-15=3(12c-5)

Answer 2

$a)3y + 3x = 3( \frac{3y}{3} + \frac{3x}{3}) = 3(y + x) \\ \\ b)3a + 3b = 3( \frac{3a}{3} + \frac{3b}{3}) = 3(a + b) \\ \\ c)3c - 3d = 3( \frac{3c}{3} + \frac{ - 3d}{3}) = 3(c - d) \\ \\ g)3v + 3 = 3( \frac{3v}{3} + \frac{3}{3}) = 3(v + 1) \\ \\ h)3 + 3p = 3( \frac{3}{3} + \frac{3p}{3}) = 3(1 + p) \\ \\ i)6a + 9b = 3( \frac{6a}{3} + \frac{9b}{3}) = 3(2a + 3b) \\ \\ m)15 - 12b = 3( \frac{15}{3} + \frac{ - 12b}{3}) = 3(5 - 4b) \\ \\ n)30a - 3 = 3( \frac{30a}{3} - \frac{3}{3}) = 3(10a - 1) \\ \\ o)36c - 15 = 3( \frac{36c}{3} - \frac{15}{3}) = 3(12c - 5)$
