0.5x-0.4 of 0.02 minus 0.5x-1 = x There is another question Given that the solution of the equation 3a-x = 2 / 2 x + 3 is 2, find the value of the square of the algebraic formula a-2a + 1

0.5x-0.4 of 0.02 minus 0.5x-1 = x There is another question Given that the solution of the equation 3a-x = 2 / 2 x + 3 is 2, find the value of the square of the algebraic formula a-2a + 1

0.5/0.02 x－0.4(0.5x－1)/0.5＝x
25x－0.4－(2x－4)/5＝x
125x－2－2x＋4＝5x
118x＝﹣2
×＝－1/59
The solution of ∵ 3a-x = (x + 3) / 2 is 2 ∵ 3a-2 = 2 ∵ a = 4 / 3
∴a²－2a＋1＝(a－1)²＝(1/3)²＝1/9

X minus two fifths x = 6 solve the equation

x-2/5x=6
3/5x=6
x=6*5/3
x=10
