Find the unknown x 9 × 3 - seventeen tenths x = 13.4

Find the unknown x 9 × 3 - seventeen tenths x = 13.4

9 × 3 - seventeen tenths x = 13.4
27-1.7x=13.4
1.7x=27-13.4
1.7x=13.6
x=13.6÷1.7
x=8

Can I move the term in the formula without unknowns, for example: 3 + 5 + 7 = 2 + 4 + 9 can I move a number on the left of = to=
Is it possible to move the term in the formula without unknowns, for example: 3 + 5 + 7 = 2 + 4 + 9 can you move a number on the left of = to the right of =

It's OK
The term shifting formula is suitable for all identities, not just equations with unknowns
Hope to help you!

3 / 4-5 × x% = 17.5

3/4-5×x%=17.5
Multiply 100 to get 75-5x = 1750
-5x=1750-75
-5x=1675
x=-335
