# The sum of two angles, #2x+10# and #3x+15# is 110 degrees. What is the value of #x#?

Solution:

Collect the like terms together by adding unknown on the right-hand side of the equal sign and taking the known on the left-hand side,

Doing so the known changes their signs from positive to negative that is;
