4/5(2x+5)−4=1 x = 1 1/4 x = 1 2/5 x = 5/8 x = 3 1/5

tia_tia [17]

The answer is x=5/8. The reason for this is when you divide it equal 0.625 then when you multiply that by 2 it equals 1.25. After you do that you add 5 which is 6.25. Now we divide 4/5 which is 0.8. Now, we multiply 6.25x0.8=5. 5-4=1. Therefore your answer is 5/8. Hope this helps :)
