5a=3a%2B10 Start with the given equation.


5a-3a=10 Subtract 3a from both sides.


2a=10 Combine like terms on the left side.


a=%2810%29%2F%282%29 Divide both sides by 2 to isolate a.


a=5 Reduce.


-------------------------------------


-5a%2B3 Move onto the given expression


-5%285%29%2B3 Plug in a=5


-25%2B3 Multiply


-22 Add


So -5a%2B3=-22 when 5a=3a%2B10
