Question

4t - (-2t-5) = 3 - 4(2t-3)

Answer 1

$4t - (-2t-5) = 3 - 4(2t-3)$

$4t +2t+5 = 3 - 8t+12$

$6t+5 = 15 - 8t$

$6t + 8t = 15-5$

$14t = 10$

$t= \dfrac{10}{14} = \dfrac{10:2}{14:2} = \dfrac{5}{7}$

Answer 2

$4T - ( -2T-5) = 3 - 4(2T-3)=\\\\4T-2T+5=3-8T+12\\14T=10\\T=\frac{10}{14}$

Bons estudos!!!
