Solve the equation 10x + X △ 10 = 45.45
10x+x÷10=45.45
Look~
10x+x÷10=45.45
100x+x=454.5
101x=454.5
x=4.5

How to solve the equation of 8x / six fifths equals five ninths
X - four fifths x = three eighths
That is: one fifth x = three eighths
X = three eighths times five
X = fifteen eighths
It is known that the equation kx2 + 2x-1 = 0 of X has two unequal real roots x1, X2, and satisfies (x1 + x2) 2 = 1. The value of K is obtained
∵ a = k, B = 2, C = - 1, and the equation has real roots, ∵ X1 + x2 = − 2K, x1x2 = − 1K, ∵ (x1 + x2) 2 = (− 2K) 2 = 4k2 = 1, the solution is k = ± 2. ∵ = b2-4ac = 4 + 4K > 0, ∵ k > 1 and K ≠ 0, so k = - 2 is rounded off, and the value of ∵ K is 2
