Answer:
3t+1)/16-(2t-3)/7=(t+3)/8+(3t-1)/14
lcm of 16,7,8 and 14 is=112
multiply each term by 112
(3t+1)/16*112-(2t-3)7*112=(t+3)/8*112+(3t-1)/14*112
(3t+1)*7-(2t-3)16=(t+3)*14+(3t-1)*8
21t+7-32t+48=14t+42+24t-8
21t-32t-14t-24t=42-8-7-48
21t-70t=42-63
-49t=-21

Answer:
mark as brainliest
Step-by-step explanation:
given,
(3t + 1)/16 - (2t - 3)/7 = (t+3)/8 + (3t - 1)/14
⇒ 7(3t-1) - 16(2t-3) = 14(t+3) +8(3t-1)
16 × 7 14 × 8
⇒21t + 7 -32 +48 = 14t +42+ 24t -8
112 112
⇒21t - 32t -14t -24t = -48-7+42-8
⇒ -49 t = - 21
⇒t = 21/ 49
⇒ t = 3/7
