combine like terms and solve

the second one turns out to have no solution.

when you simplify both sides it becomes

2x + 15 = 2x + 16 and no x could make this equal

in other terms if you subtract the 15 the problem is then

2x = 2x + 1 so the right side is always 1 higher then the right, so they are not equal
