Porfa ayudenme es urgente?

A) 5y + 4 = 3y + 6 5y - 3y = 6 - 4 2y = 2 y = 2 / 2 y = 1

b)5t + 3 = t2 + 15 5t - t2 = 15 - 3 3t = 12 t = 12 / 3 t = 4

c)6k + 5 = 2k + 1 6k - 2k = 1 - 5 4k = - 4 k = - 4 / 4 k = - 1

d)8s - 1 = 6s - 5 8s - 6s = - 5 + 1 2s = - 4 s = - 4 / 2 s = - 2

e)5(x - 2) = 3(x + 4) 5x - 10 = 3x + 12 5x - 3x = 12 + 10 2x = 22 x = 22 / 2 x = 11

f)3(h - 6) = 2(5 - 2h) 3h - 18 = 10 - 4h 3h + 4h = 10 + 18 7h = 28.
