Solving equation x (1 + 50%) * 80% - x = 28

Solving equation x (1 + 50%) * 80% - x = 28


x(1+50%)*80%-x=28
1.5x*0.8-x=28
1.2x-x=28
0.2x=28
x=140



To solve the equation: 60 △ 2-60 = (x △ 2 + 80) △ x-80 x =?


60÷(x÷2-60)=(x÷2+80)÷(x-80)
Multiply both sides by 4 (x △ 2-60 (x-80) to get 240 (x-80) = (x + 160) * (x-120)
240x-19200=x^2+40x-19200
200x=x^2
So x = 0 or x = 200



Solving equation: to process: 80% (1 + 50%) x-x = 270


80%(1+50%)x-x=270
1.2x-x=270
0.2x=270
x=5400
