How do you solve 0.3(2r-3)=0.2r+0.9

⚑ Flag

0.3 (2r - 3) = 0.2r + 0.9 0.6r - 0.9 = 0.2r + 0.9................[ expand the bracket ] 0.6r - 0.2r = 0.9 + 0.9................[ (-0.9) => (+0.9) ; (-0.2r) <= (+0.2r) ] 0.4r = 1.8 r = 1.8 / 0.4.................................[ (×0.4) => (/0.4) ] r = 4.5
