2000+15q=150-2*0.025q
2000+15q=150-0.05q
15q + 0.05q =150 - 2000
15.05q = -1,850 divide both sides by 15.05
q = -1,850 / 15.05
q = -122.92358......
+129840 2000+15q = 150 - 2*0.025q simplify the right side
2000 + 15q = 150 - 0.05q add 0.05q to both sides, subtract 2000 from both sides
15.05q = -1850 divide both sides by 15.05
q = - [ 122 + 278/301 ] = - [ 122.923588039867109634551495016611295681063122 ]
[ the decimal is of repeating length 42 ]
