If you meant 2x+3=4x²x=(1±√(13))/4x1≈1.151387818866x2≈-0.651387818866
4/28 = (4x1)/(4x7) = 1/7
13/4 = (4x1 + 3)/4 = 7/4
4X1 = four times one. 2X0.1 = two times one tenth.
4.70 = (4 x 1) + (7/10) + (0/100)
2 * - 2 = - 4 ---------------- 1 * - 4 = - 4 ---------------- - 1 * 4 = - 4 ---------------- Some of the simple ones without fractions.
Westbrook Int.
it is x=-6
27.346 = (2 x 10) + (7 x 1) + (3/10) + (4/100) + (6/1000)
by aying 4x1
x = 14
37-7 equals = 30
