The two angles given are supplementary angles so when added together need to equal 180 degrees.

2x-1 + 4x+28 = 180

Simplify:

6x +27 = 180

Subtract 27 from both sides:

6x = 153

Divide both sides by 6:

x = 25.5

i got x=25.5
because it looks like those added together equals 180 degrees so set that up as an equation than combined like terms and solve it algebraically
