Question
how do i solve variables on both sides?
for example( -15+7t=30-2t)

Use the inverse operation to get all the variables on one side or the other. Try it this way:
-15 +7t = 30 -2t add 2t to both sides because +2t is the opposite/inverse of -2t
-15 + 2t + 7t = 30 -2t + 2t
-15 + 9t = 30 now to move the -15 to the right hand side add it's opposite 15 to both sides
15 + -15 + 9t = 30 + 15
9t = 45 now 9t is multiplication so you want the inverse operation division by 9 to both sides
9t/9 = 45/9
t = 5
