t=7

Explanation:

Multiply both sides by 12 because 4 and 3 are factors of 12

12((7t+7)/4+(7t+8)/3)=33(12)

3(7t+7)+4(7t+8)=396

Distribute the 3 and 4

21t+21+28t+32=396

Combine like terms

49t+53=396

Subtract 53 from both sides

49t=343

Divide both sides by 49

t=7

Now check to see if t=7 gives 33

(7(7)+7)/4+(7(7)+8)/3=33

(49+7)/4+(49+8)/3=33

56/4+57/3=33

14+19=33
