36(t7)= 85(2t+1)
7x+265x = 5x2+x
I am not sure how to start these.
Any help?

Get rid of parentheses and combine like terms.
3  6(t7) = 8  5(2t+1)
3  6t + 42 = 8  10t 5
42 = 4t
You should be able to continue from here and do the same process with the second equation.
I hope this helps. Thanks for asking.

multiply out parentheses first
3  6 t + 42 = 8  10 t  5
combine like terms on left and on right
45  6 t = 3  10 t
add 10 t to both sides
45 + 4 t = 3
subtract 45 from both sides
4 t =  42
divide both sides by 4
t =  10.5

check
3  6 (10.57) = 8  5 (2*10.5 + 1) ????
3 + 63 + 42 = 8 +105  5 ???
108 = 108 check Caramba !
